A Scientific Study on the Composition Analysis and Microstructure of the Yucheon-ri Goryeo Whiteware

Abstract

This study examined the chemical characteristics and the microstructure of Goryeo whiteware which was excavated in the kiln site Yucheon-ri, Gangwon-do, the southern part of South Korea. this area is considered to be used in the middle of the time of Goryeo Dynasty. We analyzed the chemical characteristics comparing Goryeo Whiteware from Seo-ri, Jungam-ri, Bangsan-dong and The temple site of Beopcheon. Based on the analysis, we confirmed the properties of raw material for making pottery. It is featured that body composition of Goryeo Whiteware from Yucheon-ri contains high silica and low solvent. However, the contents of the glaze are vice versa. Goryeo whiteware tends to contain larger part of oxide than that of titanium oxide, which applies to Goryeo Celadon. the whitewares during the early days of Goryeo Dynasty varies in components depending on kilns, whereas it does not mean that chronological changes happened in components. The whiteware shards from Yuchoen-ri have a similar aspect. The whiteware shard from the temple of Beopchen differ in composition, Thus they are estimated to have been produces and shipped from various sites. In conclusion, we judged that the component difference among Goryeo whitewares stems from production environment and origin of raw materials rather than chronological changers.
