ECPN Interviews: Electronic Media Conservation with Christine Frohnert

To promote awareness and a clearer understanding of different pathways into specializations that require particular training, The Emerging Conservation Professionals Network (ECPN) is conducting a series of interviews with conservation professionals in these specialties. We kicked off the series with Chinese and Japanese Painting conservation, and now we are focusing on Electronic Media Conservation (EMG). These conservators work with time-based media, which is characterized by artwork with durational elements, such as slide, film, and video, analog or born-digital materials, performance, light or kinetic art, sound or software-based art. We’ve asked our interviewees to share some thoughts about their career paths, which we hope will inspire new conservation professionals and provide valuable insight into these areas of our professional field.

In the first interviews for this series, we spoke with emerging conservators starting in the early stages of their careers working in time-based media, which included Alexandra Nichols, Nicholas Kaplan, Brian Castriota and Yasmin Desssem. In this interview, we hear from Christine Frohnert, a conservator who graduated in 2003 from the University of Arts in Berne, Switzerland, where she majored in the Conservation of Modern Materials and Media. Prior to establishing a private practice for Time-based Media (TBM) with colleague Reinhard Bek, Christine served as chief conservator at the Museum Ludwig in Cologne, Germany for twelve years and as chair of the AIC Electronic Media Group from 2008-2012. In 2012, she was named the inaugural Judith Praska Distinguished Visiting Professor in Conservation and Technical Studies at the Conservation Center at the Institute of Fine Arts, New York University (CC/IFA/NYU), where she now serves as the Time-based Media Art Conservation Curriculum Development Program Coordinator.

ECPN: Please tell us a little bit about yourself and your current position.

Christine Frohnert (CF): I am a conservator of contemporary art with a specific focus on technology-based art. Reinhard Bek and I founded Bek & Frohnert LLC in NYC in 2012- a conservation studio in private practice specializing in the conservation of time-based media (TBM). We are both German, have been trained in Europe, worked in leading positions in museums, and have been involved in international research projects.

Bek and I focus on the conservation of artworks with a durational element in our practice—such as sound, moving image, performance, light, or movement, that unfolds to the viewer over time via slide, film, video, software, or the internet. Since the studio’s inauguration, we have responded to individual needs for both TBM conservation treatments and consulting requests. However, over the last several years, we have experienced a rising demand to serve as consultants for different U.S. institutions without time-based media conservators on staff, as well as for collectors and artists. As many TBM art collecting institutions are facing rapidly increasing needs to adequately acquire, preserve, exhibit and store TBM works, we are responding to this development and our work is more geared towards long-term collection care and the development of preservation plans, as well as education.

ECPN: How were you first introduced to conservation, what contributed to your decision to specialize in time-based media, and why has been your training pathway?

CF: As with most of my colleagues, I started conservation being exposed to more traditional media such as paintings and sculpture. About 20 years ago, I realized that technology-based artworks can be seriously harmed or lost without a new conservation specialty being established. I became fascinated with TBM, and I learned about the newly established program ‘Conservation of Modern Materials and Media’ at the University of Arts, Berne, Switzerland. I graduated from there in 2003.

ECPN: Are there any particular skills that you feel are important or unique to your discipline?

CF: A complex range of skill sets are needed, which should be solidly grounded in the conceptual framework of contemporary art conservation as a whole. It requires knowledge in electrics/electronics and programming, and an in-depth understanding of each media category, technology and its preservation, documentation and digital preservation needs. As our profession is highly collaborative by nature, soft skills are equally important to collaborate with all the stakeholders in the institutions involved, as well as with affiliated external professionals such as engineers, computer scientists, and technicians. This is important when defining, communicating, and verifying goals with vendors.

As many museums recently formed or are currently forming ‘Media Teams’ in their respective institutions to tackle their individual TBM collections needs, we have witnessed a rapidly increasing need for skilled labor, dedicated TBM lab space, equipment, and the trustworthy storage and management of huge amounts of born-digital or digitized artworks.

ECPN: What are some of your current projects, research, or interests?

CF: Currently our recent projects include consultation with several institutions to analyze their TBM collections and develop custom-designed conservation strategies according to their individual collections needs and skill sets of staff. These consultations may include surveys, assistance with media acquisitions, exhibitions and artwork documentation, storage, and migration. Bringing in external expertise often provides the bridge that many museums and their TBM stakeholders do not find in-house or do not have the capacity to coordinate. This work helps to identify and structure these needs more clearly and often provides the basis for institutional development and the implementation of larger collection care projects.

Recent and current treatment-based activities range from analyzing the ‘mechanical’ programming of a light-based work, the conservation of a seven channel-video wall from 1998 consisting of 207 Cathode Ray Tube monitors, digitization of analog video, and  the reverse engineering of custom-designed large format slide projectors, to name a few.

ECPN: In your opinion, what is an important need in your specialization?

CF: the most pressing need is education. Technology-based art is considered to be very sensitive to damage, loss, misinterpretation, and incorrect installation, due to its very specific and sensitive relationship to time, space, and concept. Damage or loss of a TBM work cannot be seen by simply examining the physical material and may not be immediately apparent unless the individual has received specialized training.

TBM conservation has been identified as a priority by many museums, collectors, and funding agencies. However, the educational opportunities are still limited, and there is currently no U.S. graduate program offering a degree in this specialty (but this will change soon!). As a result, a huge amount of our most recent cultural heritage is at risk, in an unknown condition, and/or not sufficiently integrated into museums’ missions of collecting, exhibition, conservation, research, and education.

However, thanks to the generous funding provided by the Andrew W. Mellon Foundation, the Conservation Center at the Institute of Fine Arts, NYU, started the TBM art conservation curriculum planning project in 2016.The new TBM specialization will be integrated within its current curriculum starting in fall 2018. This will be the first conservation program offering this specialty in the U.S. and the graduates will receive a dual degree: an MS in the Conservation of Historic and Artistic Works and an MA in the History of Art and Archaeology.

ECPN: Have you been involved in any advocacy, outreach, teaching or professional service roles in your specialization?

CF: During my time as EMG (Electronic Media Group) board Chair from 2008-2012, we received numerous request from the membership to offer continuing education opportunities, and in response EMG launched the conference series entitled TechFocus in 2010. The series is designed to provide hands-on guidance and systematic education on different media categories (TechFocus I: Caring for Video Art, Guggenheim Museum, NY, in 2010; TechFocus II: Caring for Film and Slide Art, Hirshhorn Museum and Sculpture Garden, Washington, DC, 2012; TechFocus III: Caring for Software-based Art, Guggenheim Museum, NY, in 2015). In addition, the first periodical worldwide that focuses on TBM art conservation was launched by the EMG in 2012, The Electronic Media Review.

At the (CC/IFA/NYU) I have offered instruction in TBM conservation art in different capacities, including the course Art With A Plug: The Conservation of Artwork Containing Motion, Sound, Light, Moving Images and Interactivity (Fall 2012 and Spring 2015).

Several professional organizations and initiatives have created additional targeted educational opportunities and collaborations. However, despite all these good developments, further training is needed at the graduate level, as well as in continuing education for professionals, to address the fast-increasing demands of TBM conservation.

Under the leadership of Dr. Hannelore Roemich, Professor of Conservation Science and TBM program Director, I have also served as TBM Program Coordinator to assist in identifying skill sets and core competencies of TBM conservators that translate into the educational needs to develop a TBM curriculum. In the fall of 2016 the Conservation Center offered the course and public lecture series Topics in Time-based Media Art Conservation, which included ten lectures by leading art historians, artists, computer scientists, and conservators. These events were an important outreach component of the curriculum development project, and they created the opportunity to promote the field, foster the dialogue between TBM professionals, and build a community.

We are now organizing the upcoming symposium It’s About Time! Building a New Discipline: Time-based Media Art Conservation to be held in May 2018. The two-day symposium will provide a forum for educators, artists, art historians, museum curators and directors, collectors, gallerists, engineers, computer scientists, and conservators to promote TBM art conservation as a discipline on an international level and will conclude the TBM curriculum planning phase.

ECPN: Do you have any advice for prospective emerging conservators who would like to pursue this specialization?

CF: While I am not comfortable issuing general advice, I can say that I personally appreciate working with students and colleagues in our field, and that this has shaped and enriched my professional life. If you are a strong communicator who is interested in the intersection of art and technology, art conservation, and art history– and maybe you even have a background in one or more of the related media fields–why don’t you join the EMG sessions at the AIC annual meetings and/or attend the upcoming NYU symposium to engage with the TBM community and find out if this specialty may be just the right fit for you?

ECPN:  Please share any last thoughts or reflections.

CF: We currently see an extremely high demand for trained TBM conservators. This can be measured by the exponentially increasing job offers worldwide and the challenges many institutions face to find qualified candidates. So, it is safe to say that this is the best moment in time for becoming a TBM conservator in this country.

ECPN Interviews: Electronic Media Conservation with Yasmin Dessem

To promote awareness and a clearer understanding of different pathways into specializations that require particular training, the Emerging Conservation Professionals Network (ECPN) is conducting a series of interviews with conservation professionals in these specialties. We kicked off the series with Chinese and Japanese painting conservation, and now we are focusing on practitioners in AIC’s Electronic Media Group (EMG). These conservators work with time-based media, which can include moving components, performance, light or sound elements, film and video, analog or born-digital materials. We’ve asked our interviewees to share some thoughts about their career paths, which we hope will inspire new conservation professionals and provide valuable insight into these areas of our professional field.

This is the third post from ECPN’s EMG blog series, for which we first interview Nick Kaplan and more recently, Alex Nichols. For our third interview from the EMG series, we spoke with Yasmin Dessem, currently Head of the Audiovisual Preservation Studio at UCLA Library where she serves as the technical lead as the library continues to develop its program of preservation, digitization and access of its moving image and sound holdings. Previously she managed archive deliverables for new feature releases at Paramount Pictures. She has experience working with a wide variety of moving image and sound formats, as well as pre-film animation devices, silent-era cameras, costumes and paper collections. Yasmin holds Master’s degrees in Art History and Moving Image Archive Studies from UCLA.

ECPN: Please tell us a little bit about yourself and your current position.

Yasmin Dessem (YD): I oversee the preservation of moving image and recorded sound materials at the UCLA Library’s Preservation Department. For nearly 90 years, the UCLA Library has collected audiovisual materials with content such as home movies, oral histories, and radio broadcasts. Examples are home movies of Susan Sontag’s parents sailing to China in the 1920s and field interviews with Watts residents after the 1965 riots. Audiovisual preservation (AV) at the library is a relatively young unit—a dedicated AV preservationist first came on board in 2011. We offer a number of in-house digitization and preservation services and are currently focusing on increasing our capacity and launching a survey.

ECPN: How were you first introduced to conservation, and why did you decide to pursue conservation?

YD: The 1996 re-release of the restored version of Vertigo first made me aware of film restoration and preservation as an actual practice. Later, as I was finishing my Masters in Art History at UCLA, I took a wonderful class on restoration, preservation, and conservation with Professor David A. Scott. The course covered the material care issues and decision-making ethics for a wide breadth of cultural heritage materials. The class struck a deep chord with me, but I was eager to graduate and start working. After graduation, I ended up working in the film industry for about six years. I was tracking down historic stock footage at one job when my mind circled back to the preservation field as I considered how the films were stored and made available. I had entertained the idea of potentially returning to graduate school to study art conservation some day, but around that time the idea of film preservation as a possible career path began to fully materialize for me. As a result, I began exploring potential graduate programs.

ECPN: Of all specializations, what contributed to your decision to pursue electronic media conservation?

YD: My longtime love for film and music intersected with my curiosity for all things historical and technology-related. These were topics that in one form or another always interested me, but I don’t think I had a full grasp on how to combine them meaningfully into a profession. Preservation was the missing key. My exposure to preservation and conservation while studying art history and my later experience working at film studios both helped direct me towards the specialization.

ECPN: What has been your training pathway?  Please list any universities, apprenticeships, technical experience, and any related jobs or hobbies.

YD: I pursued my studies in the Moving Image Archive Studies (MIAS) Program at UCLA—which persists today as a Master of Library and Information Science (M.L.I.S.) with a Media Archival Studies specialization. While in the program, I completed internships with Universal Pictures and the Academy of Motion Pictures Arts and Sciences, and volunteered at the Hugh Hefner Moving Image Archive at the University of Southern California. Throughout the two-year MIAS program, I also worked as a fellow at the Center for Primary Research and Training program at UCLA Library Special Collections, where I learned archival processing. My experiences weren’t limited to preserving moving image and sound media, but included paper-based collections, costumes, and film technology. After graduating I attended the International Federation of Film Archives (FIAF) Film Restoration Summer School hosted by the Cineteca di Bologna and L’Immagine Ritrovata.

ECPN: Are there any particular skills that you feel are important or unique to your discipline?

YD: Digital preservation will continue to be a key area of expertise that’s needed in museums and archives. Preserving the original source material and digitizing content is not enough. There are more resources than ever for strategies and tools for digital preservation, and it’s important to seek them out. Another valuable skill is developing a level of comfort with handling and understanding the unique characteristics of a wide variety of physical analog formats  such as film, videotape, audiotape, and grooved media (LP, 78s, lacquer discs, wax cylinders, etc.). Similarly, it’s helpful to have a familiarity with playback devices for these obsolete media formats (equipment like open-reel decks or video decks.) Lastly, metadata can be an unsung hero in media preservation. Often, we’re the first to see or hear a recording in decades, so capturing metadata around the point of transfer is critical. Metadata standards can be a rabbit hole of complexities, especially when it comes to describing audiovisual media, but understanding their application is an essential skill.

ECPN: What are some of your current projects, research, or interests?

YD: We’re just wrapping up digitization of materials from the Golden State Mutual Life Insurance Company (GSM), an African American-owned and operated insurance firm established in Los Angeles in 1925 in response to discriminatory practices that restricted the ability of African American residents to purchase insurance. GSM operated for 85 years and their collection is a vibrant resource documenting Los Angeles and the empowerment of a community. We received grants from the National Film Preservation Foundation and the John Randolph Haynes and Dora Haynes Foundation to support this work. The digitized collection is now available on Calisphere. We’ve just started a crowd sourcing project working with former GSM staffers to describe any unidentified content. It’s been one of the most rewarding experiences of my career, hearing everyone’s stories and seeing how much it means to everyone involved to have this collection preserved and made available.

We’ve also been in preparation to launch a large-scale survey that will help us gather data on the Library’s audiovisual collections that can be used for long term-planning. Outside of UCLA, we’ve been involved with ongoing work with cultural heritage institutions in Cuba. Last February, I set up equipment and held a workshop on the digitization of radio transcription discs held at the Instituto de Historia de Cuba (IHC) in Havana. I’m heading back there next week to begin a project to transfer IHC’s open reel audio collections.

ECPN: In your opinion, what is an important research area or need in your specialization?

YD: It’s crucial to preserve the expertise related to the operation and repair of playback equipment. Playback equipment will become more and more difficult to source in the future. Engineers, whose entire careers are dedicated to the use and care of this equipment, are some of the best resources for this knowledge. Their knowledge is shared through conversation, YouTube videos, social media, and professional workshops. Documenting the skills required to handle, maintain, calibrate, and service this equipment in a more formalized way and sharing that knowledge widely will ensure that the preservationists can keep their equipment viable for longer.

ECPN: Do you have any advice for prospective emerging conservators who would like to pursue this specialization?

YD: Try everything. Media preservation requires a wide variety of skills from computer coding to soldering decades-old circuit boards. Depending on where your career takes you, it’s good to have at least a passing familiarity with the full range of skills you may need to call upon. Apply for internships or fellowships with organizations, like the National Digital Stewardship Residency. Volunteer at community-based archives that need help getting their collections in order. Join professional organizations, like the Association of Recorded Sound Collections (ARSC) or the Association of Moving Image Archivists. Attend conferences like code4lib, the Preservation and Archiving Special Interest Group (PASIG), or the Digital Asset Symposium (DAS). Network with engineers or preservation professionals to continue to grow your own expertise, but also share your own skills when you can. Collaboration and knowledge-sharing are a fundamental part of the profession.

ECPN: Please share any last thoughts or reflections.

YD: One thing to be aware of, if you’re a woman in the field of audiovisual preservation, is that you may occasionally run into people who are surprised to see a woman working with technology (much less wielding a screwdriver!). This response persists to some degree despite the presence of many successful female professionals in the field. What’s encouraging, however, is seeing the growth of groups like the Women in Recorded Sound collective at ARSC providing support.

Audiovisual preservation is such a gratifying profession. Having the opportunity to make historic content available is incredibly meaningful work that I feel lucky to be a part of everyday. On an even more basic level, figuring out a new workflow or getting a piece of equipment to finally work is just so viscerally satisfying. I’m part of an amazing team whose passion, humor and willingness to try out new things inspires me every day and makes me feel so lucky to be doing this work.

ECPN Interviews: Electronic Media Conservation with Alexandra Nichols

To promote awareness and a clearer understanding of different pathways into specializations that require particular training, the Emerging Conservation Professionals Network (ECPN) is conducting a series of interviews with conservation professionals in these specialties. We kicked off the series with Chinese and Japanese painting conservation, and now we are focusing on practitioners in AIC’s Electronic Media Group (EMG). These conservators work with time-based media, which can include moving components, performance, light or sound elements, film and video, analog or born-digital materials. We’ve asked our interviewees to share some thoughts about their career paths, which we hope will inspire new conservation professionals and provide valuable insight into these areas of our professional field.

In our first EMG interview, we spoke with Nick Kaplan. Now for our second interview from the EMG series, we turn to with Alexandra Nichols, currently a Sherman Fairchild Foundation Fellow in the conservation of time-based media and installation art at The Metropolitan Museum of Art. From 2016-2017, she was a Samuel H. Kress Foundation Fellow in Time-based Media Conservation at the Solomon R. Guggenheim Museum. She earned her Master’s of Art Conservation from the Winterthur/University of Delaware Program in Art Conservation (2016) where she concentrated on the conservation of modern and contemporary objects.


ECPN: Please tell us a little bit about yourself.

Alexandra Nichols (AN): I received my Master’s of Conservation from Winterthur/University of Delaware Program in Art Conservation in 2016, where I concentrated on the conservation of modern and contemporary objects. I recently completed a one-year fellowship as a Samuel H. Kress Foundation Fellow in Time-based Media Conservation at the Solomon R. Guggenheim Museum, where I was working under Joanna Phillips, the Guggenheim’s Senior Conservator of Time-based Media. Just a few weeks ago, I joined the Metropolitan Museum of Art as a Sherman Fairchild Foundation Conservation Fellow, where I’ll be working with the Met’s collection of time-based media and installation art.  

ECPN: How were you first introduced to conservation, and why did you decide to pursue conservation?

AN: After obtaining my undergraduate degree in art history, I moved to London and landed a job as an executive assistant at the British Museum. While there, I visited the Hirayama Studio, the British Museum’s conservation lab dedicated to the care and treatment of East Asian paintings and works on paper. It’s a beautiful, peaceful room, with tatami mats and walls lined with brushes and different types of paper. I loved how the conservators could develop such a close, tactile relationship with the artworks, and how the treatments were carried out with respect for the cultures that created the works. This led me to seek out internships where I could gain experience in conservation.

ECPN: Of all specializations, what contributed to your decision to pursue electronic or time-based media conservation?

AN: I’m really fascinated by the wide range of materials and methods utilized by contemporary artists. Something I love about time-based media art is its complexity and variability. An artwork may have multiple channels of video, require a very specific placement in the gallery, or be shown differently based on the size or shape of the room.

My training is in objects conservation, focusing on the conservation of contemporary art. During the course of my graduate studies, none of the North American programs offered coursework in time-based media*. Thus, I was able to explore working with time-based media during my graduate internships at the Hirshhorn and the Museum of Modern Art. I’ve been pleasantly surprised that many of the time-based media pieces I’ve worked on incorporate sculptural elements, so my graduate training has been helpful in ways I didn’t expect. Learning how these objects should be placed in an installation and their relationship to electronic and audiovisual elements is really intriguing.

*The Institute of Fine Arts (IFA) at New York University is implementing a curriculum geared towards the conservation of time-based media, and is accepting applications this this year for Fall 2018 matriculation.  http://www.nyu.edu/gsas/dept/fineart/conservation/time-based-media.htm

ECPN: What has been your training pathway?  Please list any universities, apprenticeships, technical experience, and any related jobs or hobbies.

AN: I’ve always had an interest in computers and electronics. In middle school and high school, I learned the programming language C, built computers as a hobby, and took courses in video editing and digital photography as part of my undergraduate degree.

I’m originally from the Washington, DC area, and after deciding to pursue conservation, I completed pre-program internships and contracts at various museums in the Smithsonian system, including the Freer and Sackler Galleries, the Museum Conservation Institute, and the National Museum of African-American History and Culture.

In 2013, I began my graduate studies at the Winterthur/University of Delaware Program in Art Conservation, where I specialized in the conservation of modern and contemporary objects. As a graduate student, I completed a summer internship at the Hirshhorn Museum and Sculpture Garden, preparing time-based media works in their collection for the 2014 exhibition Days of Endless Time. During my third-year internship at the Museum of Modern Art in New York, I collaborated with Kate Lewis and Amy Brost to treat a pearlescent bead-adorned cathode ray tube television set by Nam June Paik and Otto Piene.

Additionally, the chance to work with Joanna Phillips at the Guggenheim has been thrilling—there aren’t many opportunities to learn about time-based media conservation in the American graduate conservation programs, so emerging conservators must gain expertise through internships and fellowships. However, this is changing soon — The Institute of Fine Arts (IFA) at New York University is implementing a curriculum geared towards the conservation of time-based media, and is accepting applications this year for Fall 2018 matriculation (link: https://www.nyu.edu/gsas/dept/fineart/conservation/time-based-media.htm). I’ll be utilizing the skills I’ve developed over the past year at my current fellowship working with the time-based media art collection at The Metropolitan Museum of Art.

ECPN: Are there any particular skills that you feel are important or unique to your discipline?

AN: Strong documentation skills are important in any specialization, but this is especially true for time-based media. The inherent variability of time-based media requires extensive research and documentation to ensure that it can be installed correctly in the future. It’s also important to know about the history of video production, including film history and the development of various formats. Foundational knowledge of video and other technologies is also crucial and has to be updated continuously, since technology is always evolving. Without this knowledge, media conservators cannot seek out and engage external specialists and vendors who can provide specific technical expertise

ECPN: What are some of your current projects, research, or interests?

AN: I am just getting started at The Met, but I am currently working with Nora Kennedy and Meredith Reiss to help document the 250 time-based media artworks in The Met’s collection. This includes updating questionnaires that are sent to artists during the acquisition process, which help us learn more about the production history and intended exhibition of the artwork, and researching past exhibitions to create retroactive iteration reports. The Met has had a Time-based Media Working Group for many years now, and I am looking forward to collaborating with its members as I conduct my research.

ECPN: In your opinion, what is an important research area or need in your specialization?

AN: I think the acquisition and display of virtual reality (VR) will pose a number of challenges for conservators in the coming years. Artists are increasingly experimenting with these types of works—Jordan Wolfson exhibited a VR work in the Whitney Biennial this year, for example—but as far as I know, no museums have acquired a VR piece yet. This technology is so new and is still being developed, and as a result, there’s so much potential for the obsolescence of file formats and hardware.

ECPN: Do you have any advice for prospective emerging conservators who would like to pursue this specialization?

AN: Try playing around with how to shoot and edit your own video in Final Cut Pro or Premiere! It will teach you about digital video formats and give you some insight into the artist’s process. And, don’t be afraid to reach out to conservators you admire to learn more about what they do!

ECPN: Please share any last thoughts or reflections.

AN: Supervised training under established media conservators is essential to the development of one’s skills as an emerging time-based media conservator. Fellowships and internships provide practical experience with real-life museum scenarios that is not possible to gain through readings or coursework. I am extremely grateful to the Samuel H. Kress Foundation and the Sherman Fairchild Foundation for providing me with opportunities to hone my expertise at the Guggenheim and The Met.

45th Annual Meeting – Opening General Session, May 30, “Preventive Conservation in the Renovation of the Harvard Art Museums: Before, During, and Ever After” by Angela Chang, Penley Knipe and Kate Smith

I was particularly interested in “Preventive Conservation in the Renovation of the Harvard Art Museums: Before, During, and Ever After” by Angela Chang, Penley Knipe and Kate Smith, as my employer LACMA is currently undergoing a similar museum building project.

Angela Chang, who presented the paper, began her talk with a brief summary of the museum’s history, which concluded with the presentation of the new LEED Gold building by Renzo Piano as well as the new storage facility that housed the entire collection during the museum building’s construction. She demonstrated how Harvard’s conservators successfully integrated the aspect of preventive conservation into an already established design and construction process. She also stressed the importance of cooperation and communication with external groups, such as administrators, donors, architects, and others, for the success of the project.

Angela discussed three main topics in conjunction with the new building.

  1. Samples of all potential and existing materials in the construction of the storage facility and the new museum were tested using the Oddy Test. Results of the tests, among other topics, were discussed in weekly construction meetings held with architects, contractors, engineers, and project managers. Only 50% of 900 tested material samples passed the test and some materials needed to be tested repeatedly due to sample mix-ups. Existing fireproofing material made of cementitious plaster, for instance, was completely removed from the storage facility for the sake of the preservation of the collection and health of humans.
  2. 300 computerized and smart, single or double blinds control the light levels in the exhibition spaces and the conservation labs, but the new museum building turned out to be more light flooded than initially expected. A seasonal programming schedule was derived from a light monitoring program based on over 50 readings and requirements from the facility department. Based on the seasonal occurrence of light leaks, conservation staff needed to identify exhibition areas not suited for light sensitive artworks and still works on permanent displayin order to safely exhibit parts of the collection. Light blocking films, for instance, are currently being tested to address light leaks.
  3. For a short time now, visitor incidents are recorded systematically and measured with a program developed by Security, Conservation, Collections Management, and IT called Art Touch Cards. The 46 guards can notify conservation and collection management staff immediately with urgent issues; minor issues are reported by filling out cards that are compiled and reviewed daily. Based on quarterly analysis of the data, artworks and galleries with a high incident rate can be identified and issues can be addressed. Improvements were made by adding colored lines of tape in the galleries as visual barriers, editing label texts, limiting the amount of visitors in one room, staffing galleries, and training guards.

Angela summarized her presentation by pointing out that all departments serve a collective purpose and that how relatively simple management systems, like the Art Touch Cards, can bridge interdepartmental communication gabs. She reiterating how the success of the building process, as well as its maintenance, is dependent on the close collaboration of different departments and external groups.

 

45th Annual Meeting – Paintings Session, June 1, 2017 – “Using Butvar® B-98 as a Consolidant for Friable Matte Paint by Claire Winfield”

Covering a pair of practical case studies, Claire Winfield’s presentation on her recent uses of Butvar® B-98 was clear and informative. Winfield, the Associate Painting Conservator at Saint Louis Art Museum (SLAM), featured two artworks that share the characteristic of having friable matte paint, but the process and purpose for consolidation of each one varied. Her ability to modify her approach for each situation was guided by research and first-hand tests with Butvar® B-98.

Molecular structure of Butvar®. Image taken during presentation.

Butvar® B-98 is one of a series of trademarked polyvinyl butyral resins, which are valued for their clarity, adhesion to varied surfaces, rheology, toughness, flexibility, and aging characteristics. Butvars® are available in a range of molecular weights (MW) and can be applied in a variety of solvents by brush or spray. They are typically used in objects conservation for materials such as deteriorated wood, stone, plaster, bone, fossils, and baskets, because they can retain a matte surface and cause little color saturation.

In both of Winfield’s featured treatments, she needed to stabilize paint without altering its optical properties – a steep challenge given their powdery surfaces. Winfield focused on the energy relationships between Butvar® B-98 and the painted surfaces, reducing the adhesive’s particle size (B-98 is the lowest MW Butvar® available) and spray applying it in multiple dilute coatings to promote penetration. Keeping the spray tip completely clean and pre-wetting the surface with solvent were helpful in this process.

The first case study was Enforcer (1962) by Larry Poons, composed of Liquitex acrylic paint and Fabspray on canvas. The Fabspray, a spray paint for fabric with vinyl and alkyd resin binders, unfortunately aged very poorly, having deteriorated to the point of actively shedding pigment. The goal of treatment was to keep the paint in place for safe dusting of the surface. Adhesive tests included Butvars® of varying weight, gelatin, and methylcellulose. Due to its small particle size, low viscosity in ethanol, strength, and minimal visual effect, a 1% Butvar® B-98 in ethanol was chosen as the consolidant. Since the Liquitex and Fabspray were applied to the painting in discrete areas, it was possible to mask the Liquitex areas while spray applying six coats of dilute consolidant to the Fabspray. The results were successful in that the paint no longer actively sheds and remains visually matte; however, the surface still cannot be safely dusted, and there was a slight but acceptable saturation of the color.

Micenic (c. 1942) by Siegfried Reinhardt, an oil painting on pressed board, was the second case study. The paint layer was locally cracked and lifting away from the board, and it was also lacking in cohesive strength: the lifting paint crumbled from brush contact and could not withstand heat. Following tests, the surface was pre-wet with 60:40 toluene:ethanol then then sprayed overall with 2% Butvar® B-98 in the same solvent mix to give the paint cohesive strength. Ethanol helped lower the viscosity of the adhesive, and toluene prevented tidelines caused by the paint’s slight ethanol sensitivity. BEVA® 371 in naphtha with heat assistance could then be applied to readhere the lifting paint to the board without undermining the cohesion provided by the B-98. This two-layer consolidation process successfully preserved both the structure and appearance of this painting.

Winfield’s work provided two responsible and creative examples for how Butvar® B-98 can be a useful addition to a paintings conservator’s toolkit.

45th Annual Meeting – Paintings Session, June 1, 2017 – “Conserving the Paintings of Romaine Brooks by Tiarna M. Doherty”

On the final day of specialty group presentations at AIC’s Chicago meeting, Tiarna Doherty, Chief of Conservation at the Lunder Conservation Center, Smithsonian American Art Museum (SAAM), rewarded attendees with a lovely presentation about the singular artist Romaine Brooks. The Smithsonian Renwick Gallery mounted the exhibition “The Art of Romaine Brooks” in 2016, and Doherty examined over 30 paintings by Brooks in preparation, many of which were featured in the show. Weaving into a captivating story Brooks’s biography, aesthetic preferences, and technical practices, Doherty also conveyed the rationale for her practical conservation approach in response to how the paintings have altered over time.

Romaine Brooks (1874-1970) is known for her stunning portraits, often featuring friends who were leading figures in the arts and humanities at the time. Born in Italy but raised in New York, Brooks’s father left when she was young, and her mother was not supportive of Brooks’s artistic pursuits. From 1890-1900, she lived in Capri with many other ex-patriots with non-traditional lifestyles; the location was a refuge following Oscar Wilde’s 1895 trials in London. Brooks met her husband in Capri, but their marriage was unsuccessful in no small part because he disapproved of her preference for masculine attire. She eventually settled in Paris in 1905. Her unpublished autobiography, which she illustrated with drawings, was titled “No Pleasant Memories.”

Brooks recorded very little about her aesthetic preferences or artistic technique, leaving only her artistic output and a few historic photographs to fill in the blanks. Her painting technique reveals some academic knowledge, though she may not have had formal training. Chalk lines and colored ground layers, such as the salmon orange preparatory layer in The Charwoman (1904), were followed by thin washes of paint and numerous glazes composed of her own mixture of oil and resin. She often used oil paint to reinforce contours on top of natural resin varnish layers to create the final surface. Painted black dashes, and in one case silver dashes, define the outer boundaries of many paintings.

In addition to painting and drawing, Brooks demonstrated an innovative attentiveness to interior design. Frame design and surface finish were clearly a consideration in her pursuit of Whistler-influenced harmony of color and tone. In one example from Doherty’s presentation, Brooks had a particular frame with a large rabbet in mind when planning a painting’s composition, as she painted the canvas only where it would show within the frame window. In another example, both the painting and the frame had a black ground layer visible beneath the finished surface – such efforts earned the accolades of “reigning in harmony” in a 1910 exhibition review.

Not surprisingly, the natural resin-containing layers of Brooks’s paintings have darkened over time. Brooks herself may even have seen the changes begin, as she chose to keep most of her paintings until her death. The presence of glazes and varnish in alternating layers with original oil paint make conservation especially challenging. In addition, conservators at SAAM observed that later applications of Paraloid® B-72, now getting cloudy, were difficult to remove safely due to sensitivity of the original materials beneath. Treatment goals leading up to the Smithsonian’s exhibition were therefore a combination minimal intervention and passive technology. When possible, degraded varnishes were reduced and surfaces resaturated. To restore some of the original cooler tonality, gallery lighting was employed to virtually compensate for some of the current altered appearance.

Doherty reminded us of Oscar Wilde’s relevant words from The Portrait of Dorian Gray, that “some things are more precious because they don’t last long.” But a conservator does what she can. This careful study of an artist and her technique led to both a thoughtful approach for displaying Brooks’s paintings, aged but still striking; as well as this transmission of her harmonious original vision.

45th Annual Meeting – Workshops, May 28-29, “Reading Between the Lines: Understanding Construction and Exhibit Design Drawings” – Collections Care Network

I participated in the “Reading Between the Lines: Understanding Construction and Exhibit Design Drawings” workshop along with 12 other conservators. During the introductions, we learned that the participants come from all over the country and as far away as Taiwan and Australia. Many had signed up in order to prepare ourselves for upcoming major renovations or new construction in our institutions. The workshop was taught by four instructors: Jeff Hirsh (Architect, Principal, Director of Cultural Practice at EwingCole), Bill Jarema (Principal, Mechanical Engineer at EwingCole), Angela Matchica (Principal, Electrical Engineer and Lighting Designer at EwingCole), and Mike Lawrence (Chief of Design at the Smithsonian National Museum of Natural History). EwingCole, an architecture, engineering, interior design, and planning firm, has worked extensively with museums and other cultural and research institutions. They recently collaborated with Mike Lawrence and Cathy Hawks (Museum Conservator at the NMNH and a participant and organizer of this workshop) on building the Q?rius Learning Space at the Smithsonian National Museum of Natural History, a permanent exhibition space in which visitors can engage with the museum collections through hands-on interactions. Much of the materials that were used in the workshop – drawings, specs, images, and group exercises – are documents from the Q?rius project.

The workshop covered a lot of ground, filling two full days during which we plunged into the complex world of construction projects. The workshop utilized a mixture of powerpoint presentations, tabletop exercises, and both planned and impromptu Q&A sessions to guide us through each step of the renovation process and help us to understand different types of construction and exhibit design documentation.

Day 1: Introduction to stakeholders, phases of design, basic terminology, reading mechanical and electrical drawings

We began with an overview of the stakeholders in a given construction project and the progression of projects from start to finish. I found it very helpful to learn about the types of documentation created during the various phases of planning and what level of detail can be expected from each phase. For example, a project starts from a concept report, which narrates the scope, timeline, and intent, progress to schematic designs, then to more detailed design development drawings, and finally to construction documents, which will go out to contractors for bidding. This lesson was supplemented by a tabletop exercise that asked the participants to find light temperature information among documentation from various phases of Q?rius design process. The exercise helped to drive home the importance of becoming a stakeholder and communicating preservation priorities at an early stage of the project, since it is becomes increasingly more costly and difficult to make revisions as the project progresses.

In the morning, we also learned basic terminology and symbols found in drawings. Because depicting the numerous things that are happening in a space – both inside and outside of the walls – is so complex, multiple drawings representing various levels of detail, multiple perspectives (elevation, plan, section), and specific categories of information are necessary. These drawings are supplemented by written documentations such as indices, keynotes, and specifications to convey the full scope of information. A reviewer must understand the system of symbols used as shorthand to indicate important information such as past edits, recent changes, the location of detail drawings, and demarcations of areas slated for demolition. At the start of the workshop, Jeff Hirsch had introduced the building as “a tool for preventive conservation”, and as the session progressed, I found it increasingly more helpful to think of the drawings as a set of instructions for using a very complex tool – in our case we are looking for ways to maximize the building’s ability to support collections preservation.

In the afternoon, we delved deeper into the different types of construction drawings by examining the general, architectural, mechanical, and electrical drawings, which each come with their own system of symbols that are used to communicate a wealth of meaning. Despite the sometimes daunting complexity of the drawings, it became clear that they follow a very specific and consistent order. I learned that when reviewing the drawings, it helps to understand them as both a set of instructions for the contractors and a legally binding contract for all stakeholders. As the latter, edits and revisions are closely tracked from version to version. Successful drawings clearly, thoroughly, and accurately communicate the scope of the project, including what is being demolished, what is being built, and what materials are being used for construction. Since each drawing can contain an overwhelming amount of information, approaching them with specific questions in mind makes them easier to navigate.

Some examples of information a conservator may need include: Do the edges of a demolition space impinge on existing collections? What are the fire ratings of the partitions slated for use in collections storage spaces, and will the fire rated partitions be fully enclosed (they must be in order to be successful)? Are there flammable materials sharing a wall with collections storage? Are smoke detectors and sprinklers located in appropriate areas? Are there enough outlets reserved for housekeeping, and are they readily accessible? What types of light sources are being used and how will they be controlled? If a new HVAC system is being installed, look to the mechanical schedules for the system’s ability to provide humidification/dehumidification and filtration information, and to the control chart for set points. Finally, with all systems that require maintenance and upkeep, it’s important to consider their proximity to collections materials, the frequency of maintenance, as well as space needs of associated personnel and equipment.

Day two: preventive conservation, exhibition design, and Q&A session

On day two, instructors began with an example in which the design team and conservators collaborated to identify an optimal pathway to move collections between the freight elevator and the Q?rius exhibit at the Smithsonian NMNH. An ideal pathway was not available, so the team mapped various options on the floor plan and used color coding to identify areas with issues such as security, access, and cleanliness. The drawing was supplemented by a filmed walk through of the actual path, which communicated potential issues with a clarity and immediacy that was difficult to convey through other media. I liked the way this example underscored the ways in which preventive conservation often relies on collaboration among parties with specializations beyond conservation, and that it focussed on an aspect of the environment – pathways – that is often overlooked when thinking about preventive conservation.

This followed with a tabletop exercise to find the outlets in the the drawings for the Q?rius space, which drove home how sometimes the little things can make a big impact on the maintenance of a finished space. In this case, it was important for us to consider the amount and location of outlets designated for a new space to make sure that enough are available for both display cases and for housekeeping use. In addition, we had to consider the accessibility of outlets for housekeeping and deduce from the drawings whether staff had to crawl into the base of display cases to reach outlets, for example. Through this exercise, we also learned that it was often necessary to switch between different sets of drawings (in this case, between electrical and exhibitions) because the information we needed was covered by overlapping specializations.

Moving further into the world of exhibition design drawings, we examined ways in which an existing space can be slightly modified to provide better climate collections objects. For example, Mike discussed an instance in which he built a vestibule as a means of limiting air exchange to an exhibit space that is located close to exterior walls and windows. In these instances the contractor schedule would be the place to look for information regarding the types of doors that are designated for use in a space.

Mike also walked us through the ins and outs of looking at drawings of custom exhibit cases, which provide detailed information on what can and cannot be done. I took a lot of notes here of factors that are important in the final product, such as: glass size (may be swapped to a different type without notice), acceptable deflection amount, potential need for levelers, desiccant chamber capacity (consider the climate of space that the case is going into), presence/type of lighting inside the cases, type of gasket used (does it actually press against the other side?), presence and composition of adhesives inside case. Getting custom cases sounded like a taxing process that was further complicated by the case builder’s use of proprietary materials.

The workshop concluded with a lively Q&A session that was populated by both questions that were pre-submitted by participants and by impromptu questions. Instructors and participants discussed questions relating to fire coding in collections and user spaces, condensation in air diffusers, preparing for a new building to be added to a museum, and considering the efficacy of using inhouse vs. outside consultants on construction projects. All in all, the workshop covered a lot of ground in two day period and offered a wealth of information that I was happy to bring back to share with my colleagues in preparation for our own renovations. I certainly felt more prepared and informed when our own construction drawings arrived at my desk several weeks later.

45th Annual Meeting – Objects Session, June 1, “Well That Didn’t Work, Now What? Stain reduction on a 10th-century Iranian ceramic” by Claire Cuyaubère and Ellen Chase

Claire’s talk highlights a topic that I’m glad we conservators are beginning to talk about more openly – treatments that didn’t necessarily work.  This subject also fit in nicely with the overall conference theme of treatment and innovation.  Although some of her treatment steps did not bring about the desired results, Claire was successful in safely and aesthetically preparing the ceramic so that it can be exhibited at the Freer Gallery of Art.

The earthenware dish features a reddish-buff ceramic body, off-white slip, and transparent glaze, with minimal brownish-black and red inscription decorations.  The ceramic was previously broken into about 40 pieces and restored, with multiple campaigns of adhesive and overpaint. The museum has records of one treatment in 1964, and while removing old repairs, Claire found evidence of at least two previous restorations which likely occurred before the object was acquired in 1954. The major condition issue was various types to staining, including general yellow and gray stains.  Additional disfiguring stain lines were present a few millimeters in from the edges of the sherds, including some areas with two or three separate rows of parallel staining.

Claire carried out analysis in an effort to determine the cause of the staining.  Using SEM-EDS, among other tools, she determined that the staining contained little iron and was primarily organic in nature, meaning it is likely not from burial but from the various restoration campaigns.  Adhesive identification was inconclusive, likely because multiple types are present; however, Claire noted the presence of hide glue, some type of acetone-soluble adhesive, and possibly shellac.  During testing, the staining did not appear to be soluble in a range of solvents, likely because of crosslinking.  Soluble salts were also identified with a microchemical test for chlorides, although no salt efflorescence was visible.  An iron-containing accretion on the back within the footring was likely from burial and was mechanically reduced to avoid transfer to other areas of the ceramic during stain reduction treatment.

Claire proceeded with stain reduction tests, following Bruno Pouliot, Lauren Fair, and Richard Wolbers’ method of three rounds of poulticing using a chelator, bleach, and a final rinse.* She ultimately chose sodium citrate (2% at pH 8) as the chelator because it was mild yet effective, and she used carbamide peroxide (20% at pH 8) as the bleach.  For both of these steps, she used agarose gel (2%) as the poultice material, favoring its ability for controlled, localized application.  The gel poultices were only applied to stained areas on the front surface of the ceramic.

Agarose gel is made by mixing the powder with water, heating to a low temperature, pouring the mixture out to cast, and then cutting into blocks when cool.  The gel blocks can then be soaked in solution; for instance, Claire soaked blocks in the chelator for one hour before applying to the ceramic.  Plastic wrap was used to cover the gel blocks while on the ceramic to reduce evaporation.  For the final rinse, the sherds were soaked in baths of deionized water, which served to clear the chelator and bleach as well as desalinate the ceramic.

To complete the treatment, the sherds were joined using Paraloid B-72, which was also bulked with microballoons and fumed silica to fill gaps and losses.  These areas were inpainted as the dish will be displayed in an art museum, as opposed to an archaeological context, and the curator preferred to have the losses integrated.

Although the staining was somewhat lightened, its appearance was not sufficiently reduced by the poulticing steps.  Claire carried out many poulticing trials, but the staining proved tenacious and she did not want to take the treatment so far as to risk causing damage to the object.  Although improvements were made, the curator still did not find the dish to be in exhibitable condition, since the staining lines were still visible and particularly distracting against the overall stark, white appearance of the ceramic.  At this point, Claire decided to try painting out the stains, over a barrier layer of B-72.  Although she did not like the idea of painting over the original ceramic surface, this seemed to be the only reasonable option for preparing the object to be exhibited and accessible to public.  Painting light over dark and matching the surrounding off-white glazed slip must have been a challenging task.  But in the end, conservators and curators were both pleased with the results!

Overall, I think Claire’s treatment was a success, and I look forward to seeing the dish on display when the Freer Sackler reopens their newly renovated galleries this fall.

45th Annual Meeting—Textiles Session, Tuesday May 30th—“Making the Mold: A Use for Fosshape in Upholstery Conservation” by Kirsten Schoonmaker and Abby Zoldowski

After much ado and various delays, I am happy to post about Kirsten Schoonmaker’s fascinating presentation!

The task at hand was creating consistent custom upholstery packages for eight Heppelwhite shield back chairs. Belonging to the Philip Schuyler Mansion State Historic site, the chairs are part of a suite of Heppelwhite pieces, which all date between 1790 and 1804. The pieces were on display when the site opened to the public in 1917. They were removed from the house in 1926, and were recovered in the 1950s, altering the profile and the show fabric. After returning to the mansion in the 1970s, the chairs were again recovered, this time in a Scalamandre fabric.

As 2017 marks the centennial of the Philip Schuyler Mansion, it was decided to return the chairs to their former glory. The chairs were suffering from saggy backs and over-stuffed arm padding, and the seats in the set featured two different profiles. Removal of the replacement show fabric and additional layers of padding on the arms of one of the chairs exposed some of the original show fabric, informing the decision regarding new show fabric. Still, a decision had to be made regarding the upholstery profile. A modern, all-archival materials solution was considered, as was the possibility of leaving all of the remaining period materials intact and part of the piece. In the end, it was decided to remove all of the additions from the 1950s restoration onward. In the case of the chair backs, whose structural condition was compromised the most, the conservators worked from the bare frame. Kirsten presented the process piece by piece, with illustrations and photographs to clarify her descriptions (a very important element for audience members with little upholstery experience like me!)

The new shield back upholstery required complex curves, which are hard to achieve when carving ethafoam. Kirsten explained the interest in utilizing the adaptable qualities of Fosshape to recreate the proper silhouette for the new upholstery packages. Both the customized shape and the resistance of set Fosshape to changes in relative humidity made the material desirable. Fosshape 600 was used to test the creation of a new chair back. The conservation team created a plywood cradle and used air-dry clay to create molds of the front and back curved pieces. The fosshape was draped over the mold and steamed to follow the correct shape. The front and back layer were then sewn together with a layer of polyester batting sandwiched between. The unified piece was then covered in muslin (and eventually a new silk fabric). Two application approaches were tried with the new shield back packages, and the effectiveness depended heavily on tack placement.

Kirsten noted several factors to keep in mind for any future experimentation using Fosshape in this manner. Addressing the inflection points and tacking edges in the mold stage would improve the process. Also, experimentation to determine Fosshape’s self-adhering qualities could prove useful in future projects. The notion of using a 3-D scanner to create a printable mold in the future could speed the process along even more. In the end, there are plenty of possibilities to take away from this fascinating project.

45th Annual Meeting — Research and Technical Studies Session, June 1, 2017 — “Revealing the text and folds in 17th-century locked letters” presented by Jana Dambrogio

The final talk of the June 1st RATS session was by Jana Dambrogio, Thomas F. Peterson (1957) Conservator, MIT Libraries, Curation & Preservation Services. Jana has been working for several years on the subject of “letterlocking,” the many techniques by which a letter can be folded to form its own envelope. Some of these letters are folded very simply while others are outfitted with complex security features that indicate if a letter has been opened by someone other than the intended recipient. Jana’s research has even suggested that a single individual might have had more than one technique for folding letters.

Most of this research has been carried out by studying unfolded letters, examining folds, cuts, and other physical evidence in order to reverse engineering the original folded structure. Now, Jana and a team from Queen Mary, University of London are using Computed Microtomography (CT scanning) to discern the interior structure of unopened letters. A collection of 600 such letters is held by the Museum voor Communicatie in The Hague, Netherlands.

The letters are part of a group of 2,600 that came to the Museum stored in a 17th century trunk. Jana explained that in the period when the letters were written, the mail operated on a “cash on delivery” system. The letters in the trunk were never retrieved, and thus remained in the custody of the postmaster. While about 2,000 have previously been opened, the “Signed, Sealed & Undelivered” project team are studying the 600 that have never been opened, using a novel application of CT imaging.

During the talk, Jana shared many videos from the project website, demonstrating techniques for letterlocking and showing the potential of the imaging technique.
