This paper is focused on a spectroscopic study of some pottery shards from an archaeological site in Syracuse (Sicily, Southern Italy), dating back to the Hellenistic–Roman period. Structural characterization was performed at different scales of observation, i.e. from macroscopic to mesoscopic. The main goal was to point out the potentiality of the small angle neutron scattering (SANS) technique as a non-invasive analytical tool in archaeometry, also in conjunction with other, more usual, methodologies. Correlation of experimental data, i.e. macroscopic typology and texture, obtained from petrographic analysis, and radius of gyration and fractal dimension of the interfaces of the mesoscopic aggregates obtained using SANS, together with mineralogical X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis, allowed hypotheses to be made on the production technology of the investigated samples. 相似文献

The masjed-i jom’e of Isfahan is one of the earliest mosques of Iran. Since 1970, Italian researchers performed an extensive archaeological investigation uncovering huge amounts of finds. This study aims at investigating the technological features and provenance of the unglazed pottery finds by using a minero-petrographic approach. Twenty-three samples of storage, table and cooking wares were selected based on the recurrence of typologically identifiable fragments and fabrics. Two bricks, seven production indicators (spacers, kiln furniture, slags) and a local clay were analysed for comparison. The production indicators and most of the pottery show high-CaO concentration. Thick-walled wares contain coarse sedimentary/metamorphic inclusions. Samples with thinner walls contain similar but fine/well-sorted inclusions. The mineralogy and microstructure indicate firing temperatures mainly ranging from 850 to 1000 °C. Low-CaO samples contain coarse sedimentary inclusions; in one sample, volcanic lithics are present. Firing temperatures range from about 800 to 950 °C, and the low-CaO character can be related to their specific function for cooking foods. One sample, found in older stratigraphic levels, differs for its peculiar calcitic temper and lower firing temperature. Local production of most samples was constrained by the composition of the inclusions compatible with the sediments of the Isfahan area. High-CaO pottery shows compositional affinity with production indicators, local clay and tiles produced in Isfahan during the Safavid period. Cooking ware usually contains local temper, with the exception of a sample with volcanic inclusions, for which a non-local provenance is supposed. No appropriate information is, however, available regarding the low-CaO clays used in the area. 相似文献
