To organize the many pieces that form just one stained glass window, artists often create full-scale drawings of the final work that serve as maps for the intricate process. Known as cartoons, these detailed templates are works of art in their own right, but they unfortunately usually receive far less exposure than their translucent counterparts. However, a team at the Corning Museum of Glass’s Rakow Research Library is currently working to conserve and digitize an immense collection of cartoons from Whitefriars Glass, one of England’s oldest glass manufacturers that operated for over 250 years. With greater access to this historic material, people across the world may search for and view the preparatory tracings of stained glass found in their local churches and cathedrals. But first, the research lab must treat each individual work, a tremendous undertaking currently spearheaded by its two interns that has yielded some fascinating finds.
