Geochemical Analysis of Etruscan Ceramic Artifacts (~700 – 200 B.C.E.), Poggio Colla, Italy
We conducted geochemical analyses to characterize the compositions of a suite of 56 ceramics (9 fine ware, 35 coarse ware, and 12 bucchero specimens) from the Poggio Colla Etruscan archaeological site north of Florence, Italy. We have to extended and refined current understanding of the ceramic industry at Poggio Colla by: 1) comparing and contrasting the compositions and textures of different ancient ceramic artifacts at the Poggio Colla site; 2) comparing the results of this study to results reported in Weaver et al. (2013); and 3) comparing the results of this study to local clay sediments that reported in Weaver et al. (2013). We used macroscopic observation, petrographic analysis, and X-ray diffraction to infer qualitative mineral compositions, and we used X-ray fluorescence to obtain the quantitative major oxides and trace element data for all 56 specimens. The primary mineral constituents include quartz, feldspar, micas (muscovite and biotite, with minor chlorite), lithic fragments and grog. The X-ray fluorescence geochemical data suggest: 1) most of the specimens have the same general geochemical composition, except for the loom weights, one antefix, and rocchetti specimens from the coarse ware group; 2) midden-originated specimens seem to have a higher concentration of CaO; 3) it is possible that all bucchero specimens and few other artifacts were imported from elsewhere because they have a different set of trace elements from the majority of the specimens; and 4) the provenance study was inconclusive, but there might be specimens of non-local provenance.
