This study focuses on the raw material characteristics, including firing temperature and the similarity of clay body, and making techniques on the underwater ceramics from offshore of Taean Mado, the Republic of Korea. The ceramic specimens include various types of celadons, Buncheongwares and white porcelains with very similar physical characteristics. All the clay bodies composed of same mineral phases within mullite and quartz, while cristobalite were also found in some white porcelains. Also, the geochemical composition of the clay body shows regular behavior properties for all the elements consisting of the celadons and Buncheongwares. In contrast, the irregular properties of trace and incompatible elements were found in white porcelains. Therefore, it is presumed that the white porcelains were made using the clay body with different source from the celadons and Buncheongwares. Notably, some white porcelains in low Th content are assumed to be made with clay formed in a different environments. Meanwhile, most of the ceramics had gone through the firing of 1,200 to 1,300℃, with some celadons fired from 1,150℃ to 1,200℃. Also, it can be interpreted as some white porcelains were fired on even up to 1,500℃.

Although the use of pottery-making soils has a long history, its use in the pottery industry requires that physical and geotechnical properties of the materials be established to define the suitability for various purposes. The main purpose of this study is to identify the different types of clays and mineral composition and to perform the geotechnical evaluation of the clays for making pottery products. Soils investigated in this study include raw materials used for making Baekja (white porcelains), Chungja (celadons), Buncheong, Sancheong, and Johyung. Pottery-making soils are manufactured by using different types of soils and sold by individual ceramic clay company. This study includes physical tests of soil and chemical analysis of major elements using XRF and XRD instrumentation. Grain size distributions, mineralogical composition, and a range of plasticities of soils for making different types of potteries are presented. Correlations between specific type of pottery clays and geotechnical and mineralogical characteristics are determined by comparing the test results. Since quantitative research using laboratory tests for pottery-making soils are rarely performed in Korea, further research should be done in the future to improve the Korean pottery industry.
