Abstract

The purpose of this study was to find out the correlation through comparative analysis of used materials and manufacturing techniques such as firing characteristics for sherds excavated from celadon kiln site in Punggil-ri, Jangheung. The color difference of the sherds was very wide, and even in the microstructure of the cross section of the glaze layer and the body layer, the celadons, whitewares, blackware, and stonewares could not be characterized because they did not show distinct differences from each other. As a result of estimating the firing temperature through the analysis of constituent minerals and thermal analysis, most of them were estimated to have been fired at 1000℃, but some were fired at high temperatures above 1200℃. It was difficult to clearly distinguish between celadon and whiteware even in the major compositional content of bodies. In the statistical analysis, glaze could be classified three group according to the type of sherds, but the bodies of celadons, whitewares, and blackware classified into one similar group. It is considered that it is not more likely differences in raw materials but some ingredients were removed or added during the purification process. Conclusionally, in this kiln site was found through scientific analysis that there were technical attempts to produce various ceramics, and that the manufacturing techniques and materials of ceramics were in an early stage that was not stabilized.

본 연구는 장흥 풍길리 출토 도자기들의 소성특성 등 제작기술과 재료학적 비교 분석을 통해 상관성을 밝혀내고자 하였다. 색차 분석결과 넓은 영역에서 분포하였으며, 유약층과 태토층의 단면 미세조직에서도 청자와 백자, 흑유자기, 도기편들이 서로 특징적인 차이를 보이지 않았다. 구성광물과 열분석을 통해 소성온도를 추정한 결과, 대부분 1100℃에서 소성된 도편과 일부는 1200℃ 이상의 고온 소성된 도편들도 있었다. 태토의 주요성분분 함량에서도 청자와 백자의 명확한 구분이 어려웠으며, 통계분석에서도 유약은 도자기의 종류에 따라 3개의 그룹으로 분류할 수 있으나 태토는 청자와 백자, 흑유자기가 유사한 1개의 그룹으로 분류된다. 이는 원재료의 차이라기 보다는 수비와 같은 정선과정에서 일부 성분이 제거되거나 첨가되었을 가능성이 높다. 따라서 다양한 도자기를 제작하고자 하는 기술적인 시도가 있었고, 도자기의 제작 기술과 재료가 안정화되지 않은 초기 단계였음을 과학적 분석을 통해 알 수 있었다.
