Sampling and analysis

Conservator Philip Klausmeyer took tiny samples from several murals to study the nature of the paint layers in cross section. Viewing the samples under a microscope, he identified binding media, surface coatings, and grime layers on the murals. This information is critical to the development of an appropriate conservation treatment.
