Jonathan Thornton has taught objects conservation at the Art Conservation Department since 1980. Following an earlier career as an artist/silversmith, he studied conservation in this department when it was still located in Cooperstown, NY, and received his M.

He completed internships in the metalwork, stained glass and woodwork/gilding departments of the Victoria and Albert Museum, and the archaeological conservation laboratories of the Museum of London. He has a strong interest in historic craft technologies, and continues to explore this area by researching period treatises, and by using and reproducing historic craft tools. His research in conservation has focused on flat glass, ivory and similar materials, and gilded and polychrome surfaces on woodwork and picture frames. He was a Rome Prize recipient in 1999, and researched the materials and techniques of molding and casting while a Fellow at the American Academy in Rome.

He also taught a tool-making workshop in Wellington, New Zealand. His publications include: "Training Ceramics and Glass Conservators at Buffalo State College: An American Perspective Illustrated by Treatment Case Histories"; "A Brief History and Review of the Early Practice and Materials of Gap-Filling in the West"; "All That Glitters Is Not Gold: Other Metal Surfaces That Appear to Be Gilded"; "Organic Colorants in Wood Polychromy"; "The Use of Non-traditional Gilding Methods and Materials in Conservation"; and "The History, Technology and Conservation of Architectural Papier Mache."
