To verifying the stability of Natural pigments for Dancheong which is available on the market was carried out as light resistance and gas corrosion test. In this particular case, we will confirm the characteristics of the only pigments except of Dancheong technique and influence of substance. Medium using for coloring are animal glue and synthetic resin that widely used for Dancheong in currently. Selected to artificial light source is a xenon arc lamp, contaminated gas is nitrogen dioxide gas in experiment. Degree of degradation of pigment were compared by measuring the degree of color change. The result of light resistance test, mineral pigments were good; color is green and blue type, soil pigments also good; color is yellow ocher, white clay, red clay etc. Gamboge, unghwang, cinnabar, red lead were confirmed not good. The result of gas corrosion test, most of the natural pigments were good condition except the red lead. Generally, animal glue samples had better than a synthetic resin samples.

회화나무는 내한성(耐寒性), 내공해성이 강하여 도심지의 공원수, 가로수로 많이 심고 있으며 수형이 아름다워 정원수로도 활용되고 있다. 또한 옛날부터 회화나무를 집에 심으면 가문에 큰 인물이나 큰 학자가 나온다고 하여 고결한 선비의 집이나 서원, 사찰, 대궐 같은 곳에 주로 심어져 천연기념물이나 보호수로 여러 지역에 남아 있다. 최근에 가로수나 조경수로 심어진 회화나무의 줄기나 가지에 혹이 있는 나무들이 쉽게 눈에 띄는데 "회화나무 녹병"에 감염된 징표이다. 회화나무에서 가장 문제가 되고 있어 이 병을 소개한다.
