Abstract

The purpose of this study was to compare the chemical properties of white soil and refined clay sediment, which are produced early in the refining process. The characteristics of the white wares made at the kiln site in Goseong-ri, Chuncheon were also examined. Three groups of materials were examined: white wares excavated from the white wares kiln, raw material from white soil collected from the surface, and a refined clay sediment group. There were also three analysis methods, which were a main components analysis, a trace components analysis, and a mineral analysis. The main components analysis found that the white wares clay was in the RO24.04~4.28 and the RO + R2O 0.30~0.31 mole areas, which were similar to the results for the refined clay sediment. However, the refining process used to produce better quality white wares meant that the large differences in the early white soil raw material appeared in the refined sediment. The mineral phase analysis showed that the crystals detected in the early white soil raw materials and refined clay sediment were almost identical. However, quartz and mullite mineral phases, which can occur above a certain temperature, were detected in the excavated white wares clay. Rare earth elements that were not affected by the pottery making process and the weathering of clay materials were found to have the same origin in all three groups.

본 연구에서는 춘천 고성리 백자가마터에서 출토된 백자 편, 백토 적치장 수습 백토 원료, 수비공 1호 내 태토 침전물 등 총 3그룹을 대상으로 재료학적 분석을 진행하였다. 연구목적은 도자기 제조과정에서 최초로 적치된 백토, 수비를 거친 태토, 최종 제작된 도자기 태토원료의 화학적 특성을 비교하고자 하였으며, 제작 완료된 춘천 고성리 가마터 백자의 특성을 살펴보고자 하였다. 분석방법으로는 주성분 분석, 미량성분 분석, 광물상 분석을 실시하였다. 주성분 분석결과 분석대상 백자의 태토는 RO2 4.04~4.28, RO + R2O 0.30~0.31 몰의 영역에서 군집하며, 수비공 1호 내 태토 침전물과 비교적 유사한 함량을 나타내었다. 하지만, 백토 적치장 수습 백토 원료와는 큰 차이가 확인되었으며, 이는 보다 양질의 도자기를 제작하기 위해 태토의 수비과정을 거치면서 발생한 결과로 확인되었다. 태토의 광물상에서는 백토 적치장 수습 백토 원료 및 수비공 1호 내 태토 침전물의 광물상은 거의 일치하지만, 출토 백자 완성품의 태토에서는 소성과정을 거치면서 소성온도에 의해 상전이 된 결과로 Quartz와 Mullite이 검출되었다. 도자기의 제작과정 및 태토 원료의 풍화과정에 영향을 받지 않는 희토류 원소는 3그룹 모두 일정한 경향성을 나타내어 동일기원임을 알 수 있었다.
