The kiln at Chollanamdo Kwangjusi Ch'unghyodong, which produced punch'ong and white wares for a period of 70 to 80 years in the 15th century, is examined for their scientific technological param-eters. Punch'ong sherds were divided into seven different groups according to the location and the layer of the waste mounds from which they were excavated. Optical and scanning electron microscope were used for microstructural observations and X-ray diffraction and polarized microscope for mineral characteristics. For determining the firing temperature, sherds were refired at different temperatures and their micro-structural changes were observed. Some wares such as the group CHE2 was high quality wares fired at high emperature around 1200$^{\circ}C$ for palace use, but as the ceramics ware became more widely used and the white wares increasingly preferred over punch'ong, lower quality wares of rougher raw materials were firedat lower temperatures around 1100-1150$^{\circ}C$ in quantity. They used local raw materials of several types, all available locally.

Jangan-eup, located in Busan, South Korea,is a famous pottery-producing area in the Joseon Dynasty period. The aim of this paper was to determine the correlation of the pottery from each kiln site of Jangan-eup by analyzing the ingredients of clay as well as its production technique and firing condition. The materials that were used for the study were fragments of inlaid celadon, white porcelain, and white porcelain painted with underglazed iron excavated from six kiln sites of Jangan-eup:Sil-li, Daeryong-li, Hajangan-li, Sangjangan-li, Yongso-li, and Dumyeong-li. In each of the samples from the six kilns, cristobalite, mullite, and quats were found. The firing temperature distinguished from the crystal structure was higher in the following order: Dumyeongli>Sangjangan-li>Daeryong-li>Hajangan-li>Yongso-li>Sil-li. The samples were divided into four groups based on the ingredients of the clayfound therein: the Sil-li andDaeryong-li group, the Hajangan-li and Sangjangan-li group, the Yongso-li group, and the Dumyeong-li group. It was also found that the sample of Dumyeong-li was made using the most homogeneous clay compared with the other samples. The pottery of Jangan-eup had $40-400{\mu}m$ glaze, had bubbles in their bodies, and had $10-150{\mu}m$ sizes.

Gaegyeong(開經), the capital of the Goryeo Dynasty (918-1392), acted as the hub for producing various potteries for the royal family, governmental offices, temples, and markets in the Gyeonggi and Hwanghae Provineces where consumptions were highly concentra
