Abstract
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.
