Table 2. Slide thickness of each finished thin section and thickness at material loss.

Thin sections were defined as finished when tissue organization was visible and identifiable using a polarizing light microscope. Select thin sections were further ground on a lapidary wheel until material integrity was lost and the thickness of the specimen when material damage incurred was measured.
