Abstract

Decolorization and discoloration of used by tradition of paintings were induced by various chemical reactions of inorganic and organic pigments due to temperature, humidity, light and air pollution and degradation of several resins combined with pigments. In this study, we made artificial samples including Azurite and Malachite as inorganic pigments on Hanji called ‘Korean Paper’ and performed natural aging test at exhibit pavilion. The chemical changes occurred by the artificial aging and the environmental effects were investigated by uv-visible spectrophotometer, FT-IR, TGA, XRD and the color changes of paintings were observed by the color-meter and video-microscope. It was found that the discoloration of paintings including Malachite was occurred at the atmosphere of acid and the radiation of UV.

초록

전통회화에 사용된 각종 색 재료 즉 유기, 무기안료나 염료는 온도, 습도, 빛, 그리고 대기 오염에 의한 각종 화학 물질 등과 직접 반응하여 탈․변색을 유도하기도 하고, 안료와 결합된 각종 수지의 열화에 의해 손상되기도 한다. 본 연구에서는 조선종이라고 불리는 한지에 석록, 석청 무기 안료를 사용해 인위적인 노화시험을 시행하면서, 동시에 전시 관에 전시를 통해 환경 요인으로 인한 자연적 노화시험을 수행하였다. 인위적인 노화와 자연적인 환경시험에 의해 일어 난 화학적인 변화는 자외선-가시광선 분광기와 FT-IR, TGA, XRD을 통해 측정하였고, 전통회화의 변색은 색차계와 video microscope로 관찰하였다. 이를 통해 석록이 포함된 전통회화의 변색은 대기 중의 산도와 자외선에 의해 일어났음을 알 수 있었다.
