An Archaeometric and Archaeological Approach to Hellenistic-Early Roman Ceramic Workshops in Greece: Contribution to Dating

The present article comprises a multidisciplinary archaeometric approach for the study of Hellenistic and Early Roman kilns in Greece. A collection of previously published and new archaeomagnetic data are combined with new results from mineralogical analytical experiments. The sampled material came from four areas, covering different geological contexts: Katerini, Olympiada, and Polymylos in mainland Greece, and the island of Paros. Extensive rock-magnetic experiments, including identification of the dominant ferromagnetic minerals present, their domain state, and mineralogical alterations during laboratory treatments, have been carried out in order to examine the magnetic properties of the studied materials and prove their suitability for reliable archaeomagnetic determinations. Magnetic cleaning provided well-defined archaeomagnetic directions, and archaeointensity measurements were carried out using both the Thellier-Thellier and Triaxe protocols. Information from both magnetic and mineralogical properties referring to firing conditions is further discussed along with archaeological information. Finally, a new dating of the four sites together with other structures of similar age was carried out using the Pavón-Carrasco model.
