One of the notable phenomena in the early stage of Korean celadon manufacture is brick-built kilns concentrated in the central region. Previous studies have shown these kilns were linked to the Chinese ceramic industry in terms of its materials and construction method and that they were significantly distinct in many ways from clay kilns found in the southern part of the Korean Peninsula.*br* A kiln of this type are discovered at Pangsan-dong 芳山洞 in Sih?ng 始興 in 1997-1998. Very well preserved relatively intact, it appears to be a milestone in the investigation of the early celadon manufacture in Korea. Three kilns were excavated at Pangsan-dong. one for celadon and the other two for earthenware. The celadon kiln was approximately 130 feet in length and seems to have undergone two massive repairs. The earthenware kilns are dated earlier than the celadon kiln and display structural similarities with those operated during the Unified Silla period.*br* Within the heaps of discarded shards between the kilns for the celadon and the earthenware, more than ten strata were detected. The lowest strata contained mostly earthenware shards, which were overlaid by a large number of kappal (shielder) fragments and celadon shards along with a relatively small number of white-porcelain shards. They show the incessant transition from the earthenware to the celadon. The celadon kiln yielded mainly soup bowls, tea bowls, and plates.*br* As regards the structure of the kiln and the manufacture-technique of porcelain, the celadon kiln display both similarities and differences compared with the S?-ri 西里 site found in Yongin 龍仁市 excavated in 1980 and the W?nsan-ri 圓山里 site in Paech'?n, Hwanghae Province discovered in 1989 to 1990. Several points could be drawn from the research on the Pangsan-dong site in conclusion.*br* First, the extensive evidence from the excavations of the Pangs an-dong kiln suggests that the Chinese ceramic technology was enthusiastically embraced, especially in the structure, style, and firing method. The styles seem to have been diversified in various regions despite initial similarity.*br* Second, although the structural properties provide no definite temporal sequence, the styles of the finds strongly indicate the kilns at Pangsan-dong, S?-ri and W?nsan-ri were contemporaneous.*br* Third, the evidnece from the Pangsan-dong kiln indicates that the first use of brick-built kilns is datable to the end of the 9th and the beginning of the 10th century. The cyclical year ksbsul 甲戌 on a fragment should be dated to 914 in stylistic comparison.*br* Fourth, the brick-built kilns in the central region including the one at Pangsan-dong were most active during the 10th century, but stopped activity at the end of the 10th century or the beginning of the 11th century except for the S?-ri kiln.*br* Flfth, the inscription Ponghwa 奉化 found at the Pangean-dong site could be equated with the Chinese region Penghua, which was quite active in ceramic industry during the Five Dynasties and early Northern Song periods in Yuezhou in Zhejiang Province. Perhaps this indicates the origin of the brick kilns transmitted to Korea in this period.
