EnglishSelected decorated Renaissance ceramic fragments, found during the excavation of a Sicilian archaeological site (Caltagirone, Sicily, South Italy), have been studied by combining scanning electron microscopy (SEM), energydispersive X-ray spectrometry (EDS), and X-ray absorbance spectroscopy (XAS). The study was aimed at providing microchemical and microstructural characterization of the colored glazed coatings in order to elucidate the nature of the pigments in the decorative layers, and in the glaze itself. From the obtained results, the general perspective has been the identification of information to be used for a reliable recognition of the production techniques. In particular, XAS measurements, performed using synchrotron radiation (SR) as the source at the Cu K-edge, in the case of green decorations, provided structural information of the oxidation states and the local chemical environment of copper (neighboring atoms and bond distances).
