Investigations by FT-IR spectroscopy on residues in pottery cosmetic vases from archaeological sites in the Mediterranean basin

Abstract

The present study was aimed at investigating, by FT-IR spectroscopy, residues in some wholearchaeological vases, different in form and dimensions, but all classified as containers for cosmetics.The analyses performed on the as-sampled material and after extraction with a solvent were examinedand compared. The results highlighted dissimilar composition of the residues for containers differentin shape and provenance. Lipids, vegetable resins, and proteinaceous compound were identified.Also some inorganic products (such as calcite or clay minerals) were found as intended ingredientsof the cosmetic preparations.The FT-IR spectroscopy provided a simple, quick and cheap analytical method, which allowsobtaining reliable and sound data using a limited preparation of the samples. In addition, thistechnique was found very useful in case of these unbroken precious artifacts, where damage hasto be avoided.
