Abstract

The Iksan Mireuksaji stone pagoda, designated as national treasure No. 11 in Korea, has been in the process of disassembling for reconstruction as part of the cultural heritage conservation program. The pagoda is mainly consisting of granite, which is relatively resistant to weathering. However, it has lost its original rock color due to various contaminants deposited at the surface since it exposed to the atmospheric environment long time. In this research, we categorized the secondary inorganic contaminants into the genetic type, and also quantitatively examined occurrences and types of pollutants in the oxidation area of the pagoda surface in which the area is clearly distinguished by naked eyes. Geochemical behavior of soluble pollutants through reaction experiments are demonstrated, and effective methods of cleaning for the conservation and scientific applicability of the surface cleaner are also studied.

국보 제11호 익산미륵사지석탑은 현재 문화유산의 원형보존을 위하여 해체복원 중이다. 이 석탑의 구성암석은 비교적 풍화에 강한 화강암으로 이루어져 있으나 오랜 세월 동안 대기환경에 노출되면서 다양한 형태의 오염물이 피복되어 원암의 색상을 잃었다. 이 연구에서는 이차적 무기오염물을 성인적 유형으로 세분하고, 육안으로 확연히 판별되는 산화 변색된 부재만을 엄선하여 오염물질의 산출상태 및 오염종을 정량분석 하였다. 또한 용해실험을 통해 가용성 오염종의 지구화학적 거동특성을 규명하고 세정방법 및 효과 등을 분석하여, 표면 세정제의 보존과학적 적용가능성을 검토하였다.
