Abstract

This study investigated manufacturing technique and provenance of the Gilt-bronze Seated Bhaisajyaguru (Medicine Buddha) Statue of Janggoksa Temple. The statue had the following : Cu(68.8%)-Sn(10.4%)-Pb(17.1%), it is similar to other medium or large Buddha statue. As results of comparison lead isotope ratio of sample with the provenance data were plotted in zone 3 of the South Korean galena map. According to this result of Bronze Buddha could be made into galena of the located in same area the temple. The results of this study were compared with the Bronze Bodhisattva statue of Goseongsa Temple. The manufacturing techniques were different based on the characteristics of Buddha statues and thus could be made into galena of the located in same area the temple.

보물 제337호 청양 장곡사 금동약사여래좌상을 대상으로 불상의 제작기술체계 및 납 원료산지를 규명하고자 하였다. 성분분석결과 구리(Cu) 68.8%, 주석(Sn) 10.4%, 납(Pb) 17.1%의 삼원합금으로 납의 함량이 높은 중 대형 불상의 주성분 조성비와 유사한 경향성을 보이고 있다. 열이온화질량분석기(TIMS)를 이용한 납동위원소비 데이터를 한반도 납동위원소 분포도에 대입한 결과 전라도와 충청도 지역에 해당하는 영남육괴 및 옥천변성대 영역(Zone 3)에 도시되었으며, 불상이 봉안된 사찰의 인근 지역에 위치한 광산에서 채취한 원료를 사용하여 제작하였을 가능성이 있다. 이어 유사시기에 제작된 강진 고성사 청동보살좌상의 제작기법 연구와 비교분석한 결과 불상의 크기 및 조성 시기, 양식적 특성 등에 따른 제작기법의 차이점을 확인하였으며, 사찰과 동일한 영역에 위치한 방연석을 사용하였을 가능성을 엿볼 수 있다.
