Electrochemical methods to discriminate technology and provenance of Apulian red‐figured pottery. II: EIS

Abstract

Electrochemical impedance spectroscopy (EIS) was applied to a set of microsamples of Apulian red-figured pottery coming from the archaeological sites of Altamura, Arpi, Conversano, Monte Sannace, Taranto, and Pella. EIS data using Fe (CN) 6 3À /Fe (CN) 6 4À as a redox probe yields information on the roughness, porosity, shape, and size distribution of inclusions in the clay body. Impedance parameters after equivalent circuit modeling permit the discrimination of manufacturing in Apulian and Attic modes as well as the characterization of the different archaeological sites.
