Abstract

This study aimed to investigate the chemical properties and production techniques for white wares from the Gwirae-1ri 3rd, Songok-3ri 2nd kiln sites in Kangwon Wonju regions. Further, another aim was to determine the correlation among the materials used to produce the white wares. The analysis of white wares in Kangwon Wonju regions produced the following results. The excavated white wares were analyzed using the Seger formula, and all the samples showed similar clay sources ($RO_2:4.33-5.82$, $RO+R_2O:0.32-0.43$) and glaze sources. Moreover, the white wares were made of host rocks of the same geological origin, according to the results of the rare earth elements analysis. When the crystalline phases of the white wares were investigated via the XRD analysis, quartz and mullite were found in all the samples, and their proportions were similar to each other. Although the firing temperatures for the samples were different, most were fired at a temperature below $1,200^{\circ}C$, with some being fired at temperatures as low as $1,000{\pm}20^{\circ}C$.

본 연구에서는 강원 원주 지역의 귀래1리 3호 가마와 손곡3리 2호 가마에서 제작된 백자의 화학적 성질 및 생산기술을 연구하고자 하였다. 그리고 수습된 백자의 제작 기술 및 사용 원료의 특징을 통하여 분석대상 백자 원료의 연관성을 규명해 보고자 하였다. 강원 원주 지역의 백자를 분석한 결과는 다음과 같다. Seger식을 사용하여 백자 태토를 분석한 결과 $RO_2\;4.33{\sim}5.82$, $RO+R_2O\;0.32{\sim}0.43$ 로 확인되었으며, 유약은 유사한 영역에서 군집하여 분포하였다. 또한, 희토류 원소 분석 결과에 따르면, 분석 대상 백자는 동일한 지질 산지의 모암으로 제작되었음을 알 수 있었다. XRD 방법을 통하여 백자 태토의 결정상을 분석한 결과, 모든 백자에서 석영 및 뮬라이트가 검출되었고, 검출 비율은 서로 유사한 결과로 확인되었다. 각 백자 시편의 소성 온도는 다르지만 대부분 $1,200^{\circ}C$이하에서 소성되었으며, 일부 백자는 $1,000{\pm}20^{\circ}C$의 저온에서 소성되었음을 알 수 있었다.
