artwork layers

artwork layers

Paintings maintained and restored in museums typically have three support layers: the original canvas, a layer of glue paste reinforced with a gauze sheet, and the new lining canvas at the back of the painting. When drugstore beetles (Stegobium paniceum) infest an artwork, they tend to attack the middle support layer, feeding on the glue paste that adheres the supportive canvas lining to the back of the original painting.
