Goryeo celadon

Timeline

1. 1371–1374Gyeonggi-do kilns · North Hwanghae ProvinceAround 1371, kilns in Gyeonggi and Jeolla provinces still fired celadon bowls, plates, and vases, with glazes mainly blue-grey and blue-green and inlaid decoration simpler than at the peak. During King Gongmin's reforms, demand for court wares and Buddhist temple offerings sustained basic production, but warfare and heavier corvée labor shrank the scale of the porcelain industry.
2. 1375–1377Busan–Tsushima sea route · South Gyeongsang ProvinceAround 1375, Goryeo used celadon as tribute to the Ming and as trade goods for Japan, with porcelain shipped from ports such as Busanpo and Gantyeok. Japanese temples and nobles still prized Goryeo celadon, and archaeological finds show that exports to Japan were not entirely cut off in this period, maintaining the peninsula's international reputation for ceramics.
3. 1378–1380Gangjin kiln sites, Jeolla-do · South Jeolla ProvinceBy 1378–1380, frequent warfare and the flight of artisans caused some famous kilns to cease production; forms grew plainer and glazes greyer. Inlaid technique rarely produced fine pieces, and although celadon remained in use as a symbol of Goryeo material culture, signs of decline toward the buncheong ware of the early Joseon dynasty were already apparent.
