Petrographic and chemical characterisation of fine ware from three Archaic and Hellenistic kilns in Gela, Sicily

This work is focused on the petro-archeometric characterization of the fine pottery production of thearchaeological site of Gela (Sicily). Thirty-five samples coming from three Archaic and Hellenistic kilnsand five coming from an Hellenistic house, were investigated by means of optical microscopy, XRD andXRF analysis. With the exception of some ceramics which are undoubtedly imported, all the samples havesimilar petrographic features, but on the basis of chemical composition, we can distinguish two differentgroups. The presence of two local productions is confirmed by the comparison with locally outcroppingsediments and with archaic and modern bricks of sure Geloan production. This result is particularlysignificant for the definition of reference groups of this wealthy polis that played an important trading role in the Mediterranean area.
