Abstract

This research conducted a component analysis and conservation treatment of "Sangryangmun," a material which had been written in 1965 and was discovered during the repair project for "Jinnamgwan" in Yeosu. The "Sangryangmun" has been stored in a cylindrical metal storage; however, defects, discolorations, hardening, and damages caused by pollutants were found. Based on the XRF analysis, rust in the cylindrical metal storage, which was made of Cu, was stuck on the surface of the "Sangryangmun". Using FT-IR and Pyrolysis-GC/MS analyses, carbonyl and compounds of fatty acids were detected; the organic material on the surface of the "Sangryangmun" was identified to have belonged to oil-based components. Therefore, it was presumed that the bast fibers of a mulberry was used in the paper. To determine the conservation materials, component analysis, condition survey, and preliminary test on adhesives were conducted. Moreover, the missing parts and partial linings were filled using mulberry-fiber paper, methyl cellulose, etc.

본 연구에서는 여수 진남관 보수 정비 사업 중 발견된 상량문(1965년 기록)을 중심으로 재질의 성분분석 및 보존처리를 수행하였다. 상량문은 금속함에 말아 보관되어 있었으며, 결손, 변색, 경화, 이물질에 의한 손상 등이 확인되었다. X-선 형광분석(XRF) 결과 구리(Cu)로 제작된 금속함에서 기인한 녹이 상량문 표면에 고착되어 있었다. 상량문 표면에 대해 적외선분광법(FT-IR)과 열분해-GC/MS(Pyrolysis-GC/MS) 분석을 실시한 결과 카르보닐기와 지방산 화합물 등이 확인되어 상량문 표면 유기물은 기름 성분으로 확인되었다. 섬유 동정 결과 닥나무 인피섬유가 사용된 것으로 판단된다. 성분분석 및 상태조사, 접착제 예비 실험 등을 바탕으로 보존처리 재료를 선정하였으며, 닥섬유지와 메틸셀룰로오즈 등을 이용하여 보강 후 부분적으로 배접하였다.
