Abstract

In this study, organic materials in Dancheong specimens were analyzed to establish a Dancheong preparation method in Unhangak Hall of Hwaryeongjeon Shrine, Suwon. IR and pyrolysis/GC/MS were applied to a Zuhong specimen and a gilded one. The IR spectra showed absorption peaks corresponding to C-O, C=O, OH, although they were different from those of animal glue, Asian lacquer, and drying oil. The Pyrolysis/GC/MS after the on-line methylation revealed Asian lacquer-derived components, such as methyl 7-(2,3-dimethoxyphenyl)heptanoate, and drying oil-derived components, such as nonanedioic acid, dimethyl ester. Based on these results, we estimated that Asian lacquer and drying oil were used in the Dancheong preparation. Small amounts of 3-methyl-1H-pyrrole were also detected, which could possibly originate from animal glue. The radiocarbon age of the specimens appeared to be between the late 17th to the early 20th century. This study potentially reports the first case of Asian lacquer detection in a Dancheong specimen in Korea.

수원 화령전 운한각의 단청기법 조사를 위해 단청시편의 유기물 성분을 분석하였다. 분석 대상은 운한각 내합 주변의 주홍과 금 단청시편이며, IR과 열분해/GC/MS분석법을 사용하였다. 분석 결과 IR에서는 C-O, C=O, OH에 해당하는 흡수peak가 나타났으나, 아교, 옻, 건성유와는 다른 스펙트럼을 보였다. 온라인메틸화 후 열분해/GC/MS 분석에서 methyl 7-(2,3-dimethoxyphenyl)heptanoate 등 옻에서 기인하는 성분과 nonanedioic acid, dimethyl ester 등 건성유에서 기인하는 성분이 검출되었다. 이로부터 단청에 옻과 건성유가 사용되었을 것으로 추정되었다. 아교 등 동물성 교착제에서 기인할 수 있는 1H-pyrrole, 3-methyl도 소량 검출되었다. 유기물의 탄소연대는 17세기 말~20세기 초로 나타났다. 단청에서 옻이 검출된 것은 처음으로 문헌상으로만 전해지는 옻칠 단청의 실체를 파악할 수 있는 자료가 될 것으로 기대된다.
