Caratterizzazione archeometrica dei mosaici del ninfeo della domus del Centenario

Vitreous tesserae from several wall mosaics in Pompii (Italy) dating around the 1st century AD have been investigated using on-site optical microscopy to sample the most relevant materials, glass, glass-cereamics, faiences. The use of complementary micro-destructive analytical techniques, such as scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRPD) allowed to define the nature of formers, fluxes, chromophores and opacifying compounds and to determine the type of raw materials employed for their introduction. The results gave an idnication of the glass technology used in the roman period.
