Analysis of red pottery bodies from South Korea using Moessbauer spectroscopy

Pottery of the Neolithic and Bronze Ages excavated from South Korea were analyzed in terms of mineral composition, firing temperature, and color factors of the pottery body based on the physical and mineralogical characteristics. In this investigation, the red pottery of the Neolithic Age was black in body color, and that of the Bronze Age was reddish yellow. All pottery body was mainly composed of quartz and plagioclase. The color factors of the pottery body were assumed by hematite and maghemite in the case of reddish yellow, and by amorphous carbon and magnetite in the case of black color. (author)
