Abstract

The Bayon style Avalokitesvara statue from the $13^{th}$ century Angkor period is on display at the Cambodia Angkor Conservation Office. This statue is composed of dark green felthspathic greywacke, the surface of which has been shown light brown discoloration, detected calcite crystallization. As a result of condition assessment, the statue was damaged due to overlap scaling and cracking. Ultrasonic tests have investigated remarkable physical weathering area, flaking and fragmentation in lower velocity. The physical condition of the statue requires a conservation method that improves the binding power. To protect against salt weathering and to ensure physical stability, new conservation material composed of mixed ethyl silicate and sandstone powder similar to that composing the statue was created. The material affected by damage was removed and replaced with the new conservation material.

캄보디아 앙코르 보존소에 소재하는 관음보살은 13세기 바이욘 양식의 석상으로, 중립의 장석질 잡사암으로 조성되었으며 석재 표면에 형성된 담갈색 풍화면에서는 방해석이 관찰되었다. 석상의 상태평가 결과, 박리와 균열의 중첩발생으로 인한 파편화 및 박락으로 인한 물리적 훼손이 심각하였다. 특히 물리적 훼손부 및 주변은 초음파속도가 낮아 입자의 결합력을 향상시킬 수 있는 보존처리가 필요한 상태였다. 이에 따라 석상의 보존환경을 고려한 염풍화의 방재 및 물리적 안정성 확보를 위하여 에틸 실리케이트계 강화제 및 석재와 유사성분의 석분을 배합하여 충전하고 노후된 보수물질을 교체하였다.
