A type of porcelain made by applying a transparent glaze over highly kaolin-rich, pure white porcelain clay and firing it at high temperatures. In China, white pottery first emerged in northern China during the late Northern and Southern Dynasties period and remained popular through the early Tang dynasty. High-fired white porcelain was produced during the Tang dynasty at kilns in Hebei Province, such as the Yizhou kiln, and continued to flourish throughout northern China, especially around the Ding kiln, until the Song dynasty. From the Yuan dynasty onward, Jingdezhen kilns became the most representative producers of white porcelain. On the Korean Peninsula, white porcelain first appeared during the Goryeo period and became widespread during the Joseon dynasty.
