Abstract

In this study, the composition of the Buddha statue surface and the plating of gold were investigated through non-destructive analysis of the gold surface, colored pigments, and sample analysis results of the plating layer on the Wooden Seated Shakyamuni at Bulamsa Temple in Namyangju from Korea. The gold surface is divided into matte and glossy parts. The matte part is a mixture of gold, titanium, and iron, so it is confirmed that gold powder and pearl mica pigment are used, and only gold foil is used in the glossy part. In the analysis of color pigments, the components of the green beard and green eyebrows are emerald green or scheele’s green, the mixed components of white and black eyes are ink (C), and the black eyes are first colored brown and then black. It is believed that the red color of the lips is cinnabar and the black color of the hair is colored with ink. As a result of the cross-sectional analysis of the plating, it is determined that it is composed of a fiber layer, a charcoal layer, and a plating layer and that soil was used inside to maintain the shape of the Buddha statue. The plating layer is made up of gold leaf and lacquer and is confirmed to be pure gold in the four layers of gold leaf. Depending on the color of the lacquer, red is chlorine, calcium, and potassium, and yellow and orange are cobalt, manganese, and iron.
