광주 우산리 백자요지 출토 도편 및 공방지 수습 원료 토양의 재료학적 상관성 연구

Abstract

This study identified the nature of objects through physical and chemical analysis of 28whiteware pieces such as White porcelain, Gapbal, and Dochim excavated in Gwangju Usan-ri 4 and9 and 14 material soil collected from Usan-ri 9, Gwangju. And confirmed material correlation betweenwhiteware and whiteware-material soil. In the case of white porcelain, it was divided into fourgroups(W1∼4) according to the color and monochromaticity of the body, and two (M1-2) groupsaccording to the Mullite peak intensity. Regardless of the kiln site, all of the high-middle-low qualitywhite pocelain were identified, and and there was no significant difference in the overall composition. As a result of particle size analysis, most of the material soil was composed of fine sand, silt, andclay. In particular, in the case of clay material soil, the main component and discriminant analysisresults showed similar tendency to white porcelain pieces. Therefore, it was estimated that the whiteporcelain excavated in Usan-ri 9, Gwangju was manufactured using material soil collected from theadjacent klin site and the production techniques of Usan-ri No. 4 and No. 9 were similar, but therewere some differences in materials.
