Through the scientific analysis of the earthenware, pottery, and roof tile excavated from this study site, it was tried to identify the physical and chemical properties of the artifacts and the correlation between the excavated points. The color difference was different among samples due to the difference of firing temperature. In cross-sectional observation, the color difference between inside and outside was clearly distinguished due to the thickness of the wall. Absorption rate was very low at less than 5% in YI-1 and YI-3, and the other samples were higher than that, but these values are similar to those of ordinary earthenware. In the mineral analysis, some of the mullite was detected, and the minerals of the spinel group were also identified. Therefore, it is estimated that four samples were fired at a temperature of about 1,100℃, but YI-5 was fired at 1,000℃ or less due to the detection of muscovite. As a result of examining the correlation between the samples, the values of magnetic Susceptibility were varied in all samples, but the ranges of values were not large. Additionally the statistical analysis using the principal element and trace element content, it was difficult to distinguish between samples. In conclusion, it is estimated that all the samples are similar to each other in terms of raw materials between building and kiln points. |
