Abstract

This study estimated the production sites by using scientific analysis of 17ea Glazed Earthenware excavated the kiln site No.17, Jinsan-ri, Haenam and 69ea excavated in Mado-shipwreck, Taean. In a previous study, the ‘Wando type’ and the ‘Mado No.3 type’ were classified by scientific analysis, which is the difference in the production sites. The kiln site No.17, Jinsan-ri, Haenam, was estimated to be a production site of ‘Wando type’ through archaeological classification, and based on this, the chemical composition of glaze and clay was compared. Most of the earthenware excavated from the No.17 Junsan-ri is made of black- brown glaze and thick clay. The Mado No.1, 2 earthenwares are also black-brown glaze and coarse particles of clay. The Mado No.3 earthenwares are smooth black-brown and green-brown glaze and thin clay. As a result of the glaze chromaticity analysis, No.17 Jinsan-ri earthenware belongs to the group ‘Wando type’, and the distribution of reflectance is also similar to ‘Wando type’. In the Non-destructive composition analysis of the glaze, ‘Mado No.3 type’ has a large distribution, while ‘Wando type’ has a high density ,and No.17 Jinsan-ri belongs to this group. As a result of observing the microstructure of the glaze, a large number of mineral particles were identified in the No.17 Jinsan-ri and ‘Wando type’ glaze, while rarely appeared in the ‘Mado No.3 type’. In the analysis of the composition of the glaze sample, ‘Wando type’ and ‘Mado No.3 type’ are distinguished and ‘No.17 Jinsan-ri’ belongs to the ‘Wando type’. By combining non-destructive and sample analysis it can be seen that the earthenware glaze of ‘No.17 Jinsan-ri’ has a high correlation of raw materials with the ‘Wando type’. As a result of the clay chromaticity analysis, it can be assumed that ‘No.17 Jinsan-ri’ is similar to the ‘Wando type’, but accurate determination is difficult due to the small number of objects for comparison. In non-destructive composition analysis, the ‘Wando type’ and the ‘Mado No.3 type’ are distinguished, and the ‘No.17 jinsan-ri’ belongs to the ‘Mado No.3 type in Rb and Sr fractions. However that does not belong to any group in statistical analysis. During sample analysis, a tendency was found to be concentrated in some ’Wando type’ in Seger formula, and the same result was confirmed in statistical analysis. In summary, it can be seen that the earthenwares excavated from ‘No.17 Jinsan- ri’ belong to the same group as the ‘Wando type’ in their glaze. A slightly different tendency in the non-destructive analysis of clay is unreliable due to the limitation of quantity, but as the sample analysis shows that it belongs to the ‘Wando type’ like glaze, it is presumed that clay also has a high correlation with the raw materials of the ‘Wando type’. As a result, it was proven through scientific analysis that the production site of the ‘Wando type’ earthenware is most likely ‘No.17 jinsan-ri, Haenam’.
