Investigation of white pigments used as make-up during the Greco-Roman period

Different white pigments were used during antiquity to prepare white make-up for women faces. Combining observations and elemental analysis with structural information, we were able to determine the mineralogical composition of cosmetics, the trace element content and the microstructure of the crystals. SEM/EDX analyses enabled us to describe the choice of materials and their preparation by grinding or chemical synthesis to obtain white pigments.
