The characterization of archaeological ceramics according to their chemical composition provides essential information about the production and distribution of specific pottery wares. If a correlation between compositional patterns and local production centers is assumed, pottery manufacturing and trade and, more generally, economic, political, as...

The study of a huge repertory of sparse glazed ware from Donoratico (Livorno, Italy) dated back to the 9th century was carried out to investigate the production technology via petrographic, chemical and isotopic investigations. The mineralogical and chemical evidence suggested the application of a lead oxide flux to an unfired non‐calcareous cerami...

The EARMEDCASTILE project, based at the University of the Basque Country, has received funding from the European Union's Horizon 2020 Research and Innovation Programme, Marie Sklodowska-Curie Action (grant agreement 656540); http://earmedcastile.blogspot.com ).

In the last decades the speciation of the cobalt complex in a glass matrix has been extensively studied. Bivalent cobalt ions in glasses of different composition commonly adopt a tetrahedral coordination, though hexa- or penta-coordinated species are also possible. Changes in the absorbance spectrum of Co-doped glasses were attested in previous stu...

The use of cadmium chalchogenide nanoprecipitates to obtain brightly coloured glasses enormously expanded by the beginning of the twentieth century, when the production of cadmium-based pigments was already well established. Six historical stained glass pieces produced between the late 1920s and modern days have been investigated in order to deline...

Until today, the evidences about the diffusion of coated bricks in Siena reported to the late XV century [1]. Six coated bricks from the Cathedral of Siena have been thus extensively studied in order to evaluate a possible older origin of the manufacture of colored tiles in the sienese context. The samples consist of some monochrome tiles of differ...

CdSxSe1-x quantum dots received considerable attention in academic studies and as cut-off filters and indirect-gap semiconductors. These glasses have also been used for artistic purposes to produce coloured glass since the 1920’s thanks to their bright colors. Since non-invasive conditions are now mandatory when considering objects belonging to the...

Six samples of coated bricks ( les) from Siena’s Cathedral have been analyzed and preliminary results are presented in this study. Coated bricks were used extensively in Italy during the 15th and 16th century, although early produc on of les, coated according to the ‘archaic’ majolica techniques, is a ested in the Mediterranean basin since the 12th...

Sixty-three pottery samples from two different urban contexts have been analyzed in order to better understand the diffusion and the possible evolution of the technological skills of the Sienese 'archaic' majolica during the Middle Ages. Samples from the first context, dating back to the 13 th and 14 th century, are from houses of nobility situated...

We focused on the behaviour of elemental distributions in unglazed earthenware artifacts. The potential role of the elemental depth profiles, as measured using a portable laser induced plasma spectroscopy (LIPS) device, in discriminating between genuine unearthed archaeological findings and modern counterfeits was investigated. Measurements were ca...
