What is the official kiln?

Official kilns were some porcelain specially burned for the court in Song Gaozong period of the Southern Song Dynasty, which was then commonly known as "official kilns". The official kiln was first located in Maogong Cave (now Yangzhou, Jiangsu). The official kiln porcelain of the Southern Song Dynasty follows the style of the Northern Song Dynasty, with regular symmetry, court momentum, elegant atmosphere and meticulous. Because of the high iron content in the tire soil, it feels heavy, and the tire soil is dark brown, which is later called "purple iron foot". The glaze is heavy and bright, thick as fat and moist as jade. Repeatedly scraping the glaze, the glaze is heavy without glare, the texture layout is regular, and the shape is solemn and generous. In addition, the "bones left by meat decay" (the exposed part looks like the bones of the dead, commonly known as "Gu Dong") was also made at that time. The official kiln we are talking about today generally refers to the porcelain fired by official kilns in past dynasties. In fact, in history, they only refer to porcelain fired in the Southern Song Dynasty, and later generations did not have this name.
