FACTURE: Conservation · Science · Art History is a new biennial journal from the National Gallery of Art that introduces the latest research on works in its permanent collection. Named for “the manner in which things are made,” the journal presents essays on conservation treatment, scientific research, and technical art history. This study undertaken at the Gallery focuses on artists' methods and materials—identifying the materials used by artists, understanding the ways in which different artists handled these materials, and discerning how to preserve the qualities the artists prized. In honor of the inaugural volume, this lecture recorded on January 12, 2014, focuses on Renaissance masterworks—painting, sculpture, textiles, and works on paper—in the Gallery's collection.
