Provenance Characterization of Archaeological Ceramics by Laser Induced Plasma Spectroscopy

摘要

Archaeological ceramics Terra Sigillata manufactured in different production centres have been studied by "laser induced plasma spectroscopy" (LIPS). The aim of this work is to demonstrate the capability of LIPS for the classification of pottery shreds in function of their provenance. Characteristic emission spectra of different pottery groups were obtained and simple linear correlation methods were used for grouping samples. In addition, complementary scanning electron microscopy coupled with energy-dispersive X-ray spectrometry (SEM-EDX) analysis were performed to obtain morphological features and to confirm chemical results.
