In this November issue of the Journal of the American Institute for Conservation, I am delighted to present six articles that encapsulate the diverse and multidisciplinary nature of our field. These articles exemplify a range of research, from practice-based investigations to technical studies, providing deep insights into the materials, techniques, and historical contexts of various artistic creations across different periods and forms. In addition, this issue includes a study on the degradation of a contemporary artwork, which is a very current and relevant topic in our field. Safety and health concerns related to repatriated objects which have been previously treated with pesticides is another problem discussed in this issue.
The journey begins with Inês Bravo's paper, which embodies practice-based research, focusing on the tailored cleaning of a J.M.W. Turner gilded frame. Bravo's work presents a meticulous strategy for removing heavy soiling and bronze overpaint from a complex oil-gilt frame, shedding light on the challenges and successes of cleaning methodologies within a limited timeframe and without sophisticated equipment.
Following this, Melissa Gardner and Corina E. Rogge’s article offers a detailed technical analysis and treatment of Zand and Qajar oil paintings. Using non-destructive methods, their study provides profound insights into the materials, techniques, and historical significance of late 18th- to early 19th-century oil paintings, enriching our understanding of these culturally significant artworks.
The third article, by Sarah K. Freeman, Michelle Sullivan, Nathan S. Daly, Karen Hellman, and Lynn Lee, investigates Daguerre's dessins-fumées, uncovering the mystery behind these architectural drawings and establishing that they were not created using photographic techniques, offering a fresh perspective on early photographic experimentation.
Moving forward, Corina E. Rogge and Bradford A. Epley delve into the pigments present in the late paintings and ephemera of Barnett Newman. Their study unveils Newman's distinctive use of paint materials, providing insights into his innovative color mixing techniques and paint formulations.
Continuing the exploration into material issues, Abed Haddad, Joy Bloser, Emily Mulvihill, and Lynda Zycherman focus on the efflorescence found on a large-scale magnesium relief by Frank Stella. Their research not only characterizes the crystalline growth but also identifies the causes behind the efflorescence, providing valuable insights for the preservation and treatment of such artworks. This paper highlights the importance not only of identifying the degradation of an object, but also the strategy for its preventive care and protection from further damage.
Lastly, Davison Chiwara, Siona Oconnell, and Maggi Loubser address an essential aspect of safety and health concerns in conservation, which is the use of pesticides in collections. Their article emphasizes the need for scientific testing, safety protocols, and the involvement of qualified conservation experts in the repatriation process of historical objects, particularly concerning potential pesticide contaminants in artifacts repatriated to African museums.
These articles not only showcase the technical expertise and scholarly depth within our field but also underscore the importance of preserving cultural heritage while ensuring the safety and well-being of those involved in conservation practices. I encourage you to delve into these insightful articles, which collectively contribute to the ongoing discourse and advancement of conservation practice and scholarship.
