Abstract

This study analyzed the chemical and mineralogical characteristics of Ridge-end tiles of the Goryeo Dynasty, excavated in Chungcheongnam-do region (Buyeo, Boryeong, and Hongseong) to examine the regional correlations and the characteristics of the production method and also compared and examined the characteristics of ridge-end tiles of Baekje Dynasty in the Sabi Period and the Goryeo Dynasty found in Chuncheongnam-do and those of the Unified Silla Dynasty found in Gyeongju in terms of the materials used by referring to the analysis data from previous studies. As a result, ridge-end tiles of the Goryeo Dynasty of Chungcheongnam-do region excluding ridge-end tiles of the Geumgangsa Temple site in Buyeo were not divided by excavation site by the composition of the clay in terms of chemical properties, but all samples showed similar trends with respect to miscellaneous components and rare-earth elements regardless of the regions. In terms of mineralogical characteristics, ridge-end tiles of the Geumgangsa Temple site is deemed to have undergone relatively high sintering temperature than other samples of similar mineral composition, and other samples did not show correlation as a variety of minerals were found from them. The chemical and mineralogical characteristics of most finals of the Baekje Dynasty in the Sabi Period are not divided by excavation site and thereby showing less correlation by remains, and they showed similar rare-earth element distribution patterns as earlier ridge-end tiles of the Goryeo Dynasty. In other words, it is highly probable that ridge-end tiles of Baekje Dynasty in the Sabi Period and the Goryeo Dynasty found in Chuncheongnam-do collected the raw materials for the clay in a fixed area when they were produced, but it is deemed that there must have been more or less differences in the process of collecting the clay from layers with different degree of aeration for each final and that they must have undergone various sintering temperatures during production. For ridge-end tiles of the Unified Silla Dynasty found in Gyeongju, relatively all samples were divided by remains in terms of chemical characteristics. It is therefore deemed that ridge-end tiles were produced by using different clays and in different production methods. In addition, it is deemed that they were produced at a lower temperature than ridge-end tiles of Chungcheongnam-do as minerals indicating relatively low sintering temperature were found compared with ridge-end tiles from the Sabi Era of the Baekje Dynasty period and the Goryeo Dynasty period regarding the mineralogical characteristics and the actual thermal analysis (TG-DSC) indicated that the sintering temperature they underwent was around 573∼870℃.
