Определение температуры и ов атмосферы обжига керамики из поселения бронзового века Каменный Амбар по данным рентгенофазового анализа

Abstract

XRD is used to determine the phase composition of the Bronze age pottery. Chlorite and calcite presence and the lack of high-temperature newly formed minerals indicate low firing temperatures (650-800°C) that are characteristic of the bonfire firing technology. The oxidiz-ing atmosphere is established for a number of ceramic fragments due to the presence of iron oxidized compounds (hematite and goethite). The quantitative data on the additive content (talc, calcite, etc.) in pottery is obtained.
