Abstract

The Nongso tomb of Sunchang was built in a relatively deep place; hence there was little damage from grave robbers. The tomb was completely filled with a large amount of charcoal, and therefore the wooden coffin was excavated in relatively good condition. On the basis of the structure of the tombs, excavated artifacts, and radiocarbon dating results, the tomb is estimated to be from between the late Goryeo and the early Joseon period. The wooden coffin excavated is double-layered structures consisting of an outer coffin and an inner coffin. The outside of the wooden coffin is thickly lacquered and decorated with yellow letters and white motifs. An analysis of the pigments' components revealed that the major component of the letters was gold (Au) and the major component of the motifs was silver (Ag). The coffin lacquer had three layers: a pigment layer, a yellowish-brown layer, and a black layer. The wooden bases of the coffins were painted with a black substance, such as soot, as mineral elements were not detected in the black layer. The yellowish-brown layer is presumed to be refined lacquer. From the analysis of the structure of the layers and pigments, we can estimate the method was adopted for making lacquer for wooden coffin. It is assumed that the method used gold leaf and gold powder. The form of the pigment and the internal structure are likely to be gold leaf, but the shape of the surface letters appears to have been formed using gold powder. This study will serve as important information for understanding lacquer making techniques at the time of the tombs' construction by confirming the making method through reproduction experiments using gold leaf and gold powder.

순창 농소고분은 적성면 운림리 일대와 내월리 농소마을을 둘러 형성된 구릉지 능선에 위치하고 있다. 고분의 토광은 비교적 깊은 곳에 조성되어 도굴의 피해가 없었으며 전체적으로 다량의 숯으로 채워져 있어 목관이 비교적 좋은 상태로 출토되었다. 고분 구조 및 매장시설, 출토 유물, 방사선탄소연대 측정 결과를 종합하였을 때 농소 고분의 축조시기는 고려시대 후기부터 조선 초기까지로 추정하고 있다. 농소고분에서 출토된 목관은 목곽과 목관의 2중 구조로 목관 외면에 두껍게 옻칠을 하고 금색 문자와 흰색 문양으로 장식되었다. 안료 분석 결과 금색 문자는 금(Au), 흰색 문양은 은(Ag)이 주요 성분으로 확인되었다. 칠 막은 안료 층, 황갈색 층, 검은 층의 3개 층으로 관찰되었다. 검은 층은 그을음과 같은 검은 물질로 목재 바탕의 밑칠로 사용되었다. 황갈색 층은 옻칠로서 정제칠로 추정된다. 목관 칠막 분석을 종합하면 칠 제작방법은 금박을 이용하는 방법과 금분을 이용하는 방법으로 추정된다. 안료 형태 및 내부 구조상으로는 금박이 유력하지만 표현된 글자의 형태를 보면 금분을 이용한 것으로 보인다. 따라서 향후 금박과 금분을 이용한 재현실험을 통하여 제작방법을 확인한다면 고분 축조 당시 칠기 제작기술을 파악하는데 중요한 자료가 될 것이다.
