Abstract

The Grave encapsulated by lime soil mixture were excavated with clothing and hemp shoes from the Choseon Dynasty in Gooam, Sacheon. Hemp shoes have wood in the center and their surroundings were made of complex materials including herbaceous ones but the front part was lost or became very fragile. We analyzed the hemp shoes and pre-test of consolidant for conservation treatment of hemp shoes. As a result of analyzing, three kinds of plants were identified. For hemp shoes, Oryza spp, hemp, and one kind of dicotyledones were used and it was analyzed that fabrics attached to the back of Dogaengi was cotton. Conservation methods for pre-test of consolidant, Polyethylene Glycol, Paraloid-B72, Dammar gum, Methyl Cellulose and Silicone resin was selected. The solution was sprayed twice in a 24-hour duration. Properties of consolidant was measured; color difference, glossiness difference, folding streangth and tensile streangth. By comparing the results, PEG was confirmed to the most suitable as consolidant. For the conservation treatment, cleaning and strengthening was conducted. For strengthening treatment, PEG 4000 was selected given that the shoes were made of complex materials. The PEG impregnation method was applied with the PEG 4000 concentration gradually changing from 5% to 80% for reinforcement. Then humidity- controlled drying in order to avoid any rapid environment change.

사천 구암 발굴현장 내 출토된 조선시대 회곽묘에서 복식류와 함께 미투리가 출토되었다. 미투리는 목재와 초본류로 제작된 복합재질로 앞총부가 소실되거나 매우 약한 상태로 수습되었다. 보존처리를 위하여 미투리에 대한 과학적 재질분석과 강화제 선정 예비실험을 먼저 진행하였다. 재질 분석 결과, 미투리는 벼속(Oryza spp.), 마섬유, 쌍자엽식물 1종이 사용됨을 확인하였으며 또한 뒤쪽 도갱이에 붙어있었던 직물은 면섬유로 분석되었다. 강화제 선정을 위해 약품 5종(Polyethylene Glycol, Paraloid-B72, Dammar gum, Methyl Cellulose, Silicone resin)을 선정하여 예비실험을 실시하였다. 색차, 광택성, 내절강도와 인장강도 변화를 약품별로 측정하여 결과를 비교하여 PEG를 강화제로 선정하였다. PEG는 색도 및 광택변화가 적고, 인장강도가 높게 확인되어 가장 적합한 것으로 판단되었다. 미투리 보존처리는 클리닝 후 PEG 4000을 5%에서 80%까지 농도를 높여 유물에 견고성을 부여하였으며 조절건조를 통해 보존처리를 완료하였다.
