Abstract

This study classified types of glazed earthenware excavated from Madoshipwreck in, Taean, and presented scientific grounds for type classification by using scientific analysis of 69 glazed earthenware pieces. The scientific analysis is divided into nondestructive analysis, such as chromaticity, reflectance analysis and chemical composition analysis(p-XRF), and sample analysis such as microstructure observation(SEM), chemical composition analysis(EDS, WD-XRF) and crystal structure analysis(XRD). According to the archaeological classification, the glazed earthenware excavated from Mado shipwreck classified as “Wando type” for Mado No.1, 2, and “Mado No.3 type” for Mado No.3. As a result of the scientific analysis, the same raw material was probably used for the glaze and clay of Mado No.1 and No.2(Wando type) due to their similar chemical composition and tendencies. The glaze and clay of Mado No.3 tend to be different from “Wando type”, so “Wando type” and “Mado No.3 type” are different in raw materials and production areas. In addition, thereliability of measurement results of nondestructive analysis and sample analysis are slightly different, but the analysis results are classified according to the archaeological classification characteristics. Therefore, for samples that are difficult to collect, the possibility of type classification analysis can be suggested by using the nondestructive analysis method first.
