Preliminary chemical characterization of Roman glass from Pompeii

摘要

Eleven fragments of Roman glass were analysed by XRF (X-ray Fluorescence) and LA-ICP-MS (laser ablation inductively-Coupled Plasma Mass Spectrometry) to determine major, minor and trace elements, including rare earth elements. The fragments come from the archaeological site of Pompeii (Naples, Italy) and belong to various types of blue-green glass objects. Analytical investigation of glass was performed in order to determine which melting, colouring and pacifying techniques were adopted to prepare these materials. The results indicate that the samples, dated to the first century A.D., before A.D. 79, by archaeological suggestions, are soda-lime-silica glass, obtained by using pure sand, natron and recycled glasses. Colouring, decolouring and opacifying agents were not used.
