Abstract

This research aims to examine compositional and microstructural properties of grayish-blue-powdered celadon in Wonju Beopcheon-temple site. X-ray fluorescence sequential spectroscopy (XRF) with micro-point analysis, scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) were applied to determine the chemical composition, microstructure and crystallinity of samples, respectively. As a result, the average compositions of bodies were low silica ($RO_2$) and high flux (RO+$R_2O$). Owing to the high content of calcium oxide the glaze is considered lime type between limealkali type. The body of celdon sheard was found quarts, mullite, microcline, albite. Especially, the body's chemical compositions were compared to the results of previous studies by using a Seger formula. The compositional properties of Grayish-blue-powdered celadon in Wonju Beopcheon-temple site showed diffrently from the the other grayish-blue-powdered celadon.

본 연구는 원주 법천사지에서 출토된 분청사기의 화학조성과 미세조직, 결정상을 X-선형광분석기와 주사전자현미경-에너지분산형엑스선분석기, X-선회절분석기를 이용하여 알아보았다. 태토의 화학성분 분석 결과, 낮은 실리카($RO_2$) 함량과 높은 융제(RO+$R_2O$) 함량임을 알 수 있다. 유약의 경우 융제 성분 중 CaO 함량이 높은 전형적인 석회계열(lime type)과 석회-알칼리 계열(lime-alkali type) 유약을 사용하였으며 태토의 결정상으로는 quarts, mullite, microcline, albite가 확인되었다. 특히 원주 법천사지에서 출토된 분청사기 태토의 화학적 조성은 제겔식을 이용하여 이미 연구된 다른 유적에서 출토된 분청사기와 비교하였으며 화학조성은 서로 상이한 결과를 보였다.
