감은사지서삼층석탑의 표면오염물과 세척사례 조사 연구는 부재 표면에서 관찰되는 무기오염물의 성분분석과 오염물 제거 방법을 선정하기 위해 실시하였다. 표면오염물 조사는 육안관찰과 주사전자현미경, XRD를 이용하여 오염물의 상태를 파악하고 정성․정량분석을 통해 비교․분류하였다. 분석결과, 표면오염물은 철화합물이나 황화합물 등 화합물로 존재하며, 결정 형태는 원형, 타원형, 침상, 각형이 주를 이룬다. 오염물을 제거할 수 있는 방법을 검토한 결과, 미립재를 와류형식으로 분사하는 저압와류세척방법이 적당한 것으로 사료된다.

Analytic research on the surface pollutant of the three storied-pagoda at the west of Gameunsaji site as well as studies of previous wet cleaning cases was undertaken in order to decide cleaning method for removing inorganic pollutants. The status of pollutant was examined by naked eye observation, SEM-EDS, XRD. Then it was compared and categorized through qualitive and quantitative analysis. The result showed that the surface pollutants consisted of iron compounds or sulfur compounds and it was crystallized in the form of circle, oval, needle, etc. Result, Low-pressure rotating vortex process cleaning, with which particular matters are sprayed in swirl, is considered to be the best method to remove the pollutants.
Key Words: Gameunsaji West stone pagoda, Surface pollutant, Cleaning, Low-pressure rotating vortex process cleaning
