Pumice, a lightweight volcanic rock, was used in ancient times as a cosmetic remedy and also as an abrasive. A product of high demand, it unleashed an intense commercial activity among Egyptian, Syrian, Minoan and other Mediterranean cultures. In Egypt, pumice has been found in ancient workshops. In some of the excavations, there was even rock that still presented the right abrasion traces. They were used to polish sculptures, constructions, bronze objects, and so forth.
Based on pumice specific chemical composition, researchers from Vienna University of Technology can generate a chemical fingerprint and compare rock types from archaeological excavations to determine their origin. Egyptians have surely ordered pumice from Greece.
