Paint sampling

Sampling and analysis of the paint was another vital part of the examination process. Information gained during analysis helped to guide the conservators during the cleaning process. To sample a painting, a conservation scientist removed a tiny chip of the paint with a surgical scalpel, usually from the edge of pre-existing loss. The sample was mounted in resin, and viewed under high magnification in cross-section. Conservators gleaned a great deal of information about the layers of paint applied by the artist, the nature of the dirt that deposited on the surface, and the presence of any coatings.
