Data on raw materials and plaster recipes: the Greek, Hellenistic and Roman cetariae of Portopalo (Sicily, Italy)

The purpose of this dataset is to provide access to all the data collected during the study of 22 plaster samples from varius fish-salting vats discovered at the archaeological site of Portopalo di Capo Passero (Sicily, Italy). The site has a long and complex chronology, from the 5th century BC to the Late Roman period (4th–5th century AD), including multiple phases of occupation. All the vats were coated with lime plasters that were sampled and analysed by chemical, mineralogical, and petrographic techniques (OM, SEM-EDS, XRD, XRF, IC). The dataset includes a brief description of the samples with sampling points and the methodology used. The analysis results are divided by technique and organized in different folders.
