The scientific analysis of potteries-Focus on the potteries excavated from kiln sites at Jeonla Nam.Buk-do

도.토기의 과학적 분석-전라남.북도 도요지 출토 토기편을 중심으로

The scientific analysis and provenance study of potteries excavated from kiln sites at Jeonla Nam. Buk-do were carried out using XRD,ICP-AES and NAA. We can summarize the following consequence. First, as a result of XRD analysis, it showed that soft potteries consist of quartz, feldspar and clay minerals while hard potteries consist of high temperature crystals such as mullite, tridymite, cristobalite. In case of firing temperature which are determined by crystals using XRD, potteries are composed of quartz, feldspar and clay minerals had very low firing temperature. While potteries having only cristobalite ranged above$1200^{\circ}C$. Second, as a result of correlation analysis using trace element, the selected characteristic elements which was able to distinguish from each kiln site was Ce, Lu, Cs, Sc, Eu. Third, discriminant analytical results showed that kiln site of the Jeonla Namdo were classified into five groups and that of the Jeolna Buk-do into three groups. This suggests that there are no correlations between the raw materials used in each kiln sites.
