Punch'ong and whiteware sherds excavated from four kilns located in Ch'unghyodong, Kwangju, Choilanamdo were analyzed for their body and glaze composition. They are classified into eight different groups by the site and layer from which they were collected. In principal component analysis of major composition, the punch'6ng body separates out into several different groups. CHE2, made in early fifteenth century, has a higher aluminum and lower iron content compared to the later groups of lower grade. Whiteware body has a very high aluminum content of around 30 wt.% in both soft type and hard type. Punch'6ng glaze was determined to be lime type and whiteware alkali-lime type.
