Stained Glass Conservation

http://www.sciencefriday.com
Medieval stained glass reveals a lot about life in the Middle Ages, but keeping these artistic works from falling apart is a detailed process. Hanne Roemich from New York University's Conservation Center and Brooklyn-based conservator Mary Clerkin Higgins discuss the science behind glass conservation, and how these centuries-old relics are protected from the natural elements so we can enjoy them for years to come!
