The scientific analysis of potteries-Focus on potteries excavated from kiln site at Gyeongsang Nam-do

도.토기의 과학적 분석-경상남도 도요지 출토 토기편을 중심으로

The scientific analysis and provenance study of potteries excavated from kiln site at Gyeongsang Nam-do were carried out using XRD, ICP-AES and NAA. We can summary the following Result :1. As a result of XRD analysis, it showed that soft potteries consisted of quartz, feldspar and clay minerals while hard potteries consisted of high temperature crystals such as mullite, tridymite, cristobalite.In case of firing temperature which are determined by XRD, potteries consisted of quartz, feldspar and clay mineral had very low firing temperature. While potteries having only cristobalite ranged above $1200^{\circ}C$.2. As a result of correlation analysis using trace element, the selected characteristic elements which was able to distinguish from each kiln site was Sm, Cs, Sc, Eu, Hf.3. Discriminant analytical showed that each kiln site were classified into 4-gruops;Kimhaeci Daesungdong, Hamangun Myosari, Changyounggun Yochori and one group mixed KimhaeciGuosandong, Kimhaeci Samgyeri. This suggests that there are no correlations between the raw materials used in each kiln sites except Kimhaeci Guosandong, Kimhaeci Samgyeri.
