Abstract
In 2016 a huge amount of archeological materials, mainly painted architectural slabs, were retrieved from the Glyptotek of Copenhagen and the private collection of R. Syme thanks to an action of the Comando dei Carabinieri della Tutela Patrimonio Culturale. According to the analogies in style and the typology part of these materials are supposed to come from the UNESCO archeological site of Cerveteri, important Etruscan center to which belong a large amount of materials dated back to the second half of the VI century B.C. Due to the importance of these precious terracotta, all the specimens were investigated by means of non-destructive portable XRF and Raman instrumentations. Furthermore, XRD and micro-Raman spectroscopy were carried out on micro-samples picked up by the restorers of Superintendence. The research aims are: i) the individuation of the main chemical and mineralogical composition of the pottery bulk; 2) the characterization of the painted layers. The data obtained were compared with those carried out on similar fragments certainly attributed to Cerveteri and Veio. Furthermore, the use of pigments was related to the colors used in the archaic period for the Tarquinia [1] wall painted tombs. The slabs, all with a creamy engobe, show human and animal figures in geometrical frameworks. Combined Raman and XRF analysis allowed us to distinguish different pigments and to suggest some considerations about their authentication. [1] G. Barone, P. Mazzoleni, A. Cecchini, A. Russo. 2018.
