초록/요약
Korea experienced a tragic loss of most of the Sungnyemun building in an arson attack in 2008. Few scientific records of the pigments originally used in the Korean national treasure exist, thus, the restoration of Sungnyemun was a serious failure. Because the Raman spectroscopic method has the advantage of analyzing the pigment phases in a simple, nondestructive, and noncontact way, it is becoming more important in scientific research on the colors present in cultural assets. In this study, Raman mapping measurements of the pigments in several "dancheong" - color decorations of the surfaces of the wood structure of Korean buildings - samples from Bongjeongsa Geukrakjeon and Sunglimsa Bogwangjeon are presented. The distribution of the pigments, which is difficult to observe with the naked eye, can be found in detail through a high-resolution Raman mapping image. A change of Raman spectrum due to the powderization of some pigments in the colored layer is also observed. The powderization of the pigments is considered to be due to weathering. Our Raman study will be helpful for the preservation and restoration of cultural heritage in general.
