Abstract
Analyses of the three-storied stone pagoda at the Bulguksa temple in Gyeongju were carried out in order to identify the cause for material characteristics of inorganic contaminants and conservation treatment materials. Results indicated that foreign soil or weathering soil caused yellow discoloration of the pagoda, reddish-brown contaminants were formed by goethite (FeOOH), an iron oxide mineral, and black pollutants were formed by manganese (Mn) oxide, leading to discoloration of the rock. Among the restoration materials used in the past, cement mortar could cause whitening by reacting with the external environment. The results were used as basic standards to evaluate the material characteristics of the surface contaminants and identify a set of effective conservation treatments. Nevertheless, continuous monitoring is required, as there is a high possibility of regeneration of pollutants in the future because of the continuous exposure of the pagoda to the external environment.
