This study was to identify the material characteristics and provenance of the crucibles, potteries and roof tiles from the Wonsinheungdong site in Daejeon, Korea.Similar mineral composition of each samples showed by microscopic observation and X-ray diffraction analysis.However, thickness and mineral characterization of each ceramic artifact are quite different.The pottery is characterized by thin body with 0.5 to 0.7cm and fine grained clay matrix.While the crucible and roof tile has thick body with 1.3 to 2.5cm, poorly sorted texture of many quartz, orthoclase and plagioclase within ceramic fabric.And large elongated voids formed by hydrocarbon of straw during the firing and loose matrix observed in crucible.All ceramic samples and ground soil of the site show similar mineralogical characteristics geochemical behavior and clay-mineralization degree.This indicates making that the soil is probable to be a raw material of all ceramic from the Wonsinheungdong site.Also, firing temperature of most ceramic artifacts are estimated at 850 to 950℃ but hardest pottery fired high temperature between 1,050 to 1,150℃.The vitreous molten materials interpreted in slag included segregation of copper and tin.But it cannot exclude the possibility that the glass molten material because observed reddish and greenish vitreous fine structure under microscopic.
