Analysis of Roman era archaeological finds from Museo Territoriale del Lago di Bolsena with non-destructive investigation techniques

The management of the Museo Territoriale del Lago di Bolsena has made various types of archaeological finds available for non-destructive and non-invasive analysis using advanced techniques. The finds date from the Roman period and were collected during the excavation campaigns of the French School in the archaeological area of Poggio Moscini in the town of Bolsena (Viterbo) between 1962 and 1973. The finds on which the analyses focused are: metallic handles, pots and mosaic tiles. The techniques used to carry out this archaeometric study are based on X-ray diffraction (XRD). In addition, Raman and Fourier-Transform IR (FTIR) spectroscopies in the reflection mode have been considered for the characterisation of the finds. The content of this paper is part of the research activity of the project REMEDIAVI (Ricostruzione virtuale ed in realtà aumentata di Volsinii Novi: un approccio avanzato per la fruibilità sostenibile dell'area archeologica di Bolsena).
