How do porcelain mud distinguish good or bad?
Compared with the international standard of the kaolinite content Chinese, southern Suzhou and Fujian Longyan kaolin soil Si was significantly more than the commonly used North Datong soil, iron content and mix the raw is significantly larger, but the north and south to kaolin aluminum content than the British standard used for EPK, which also makes the general China porcelain to temperature higher than 1310 degrees, or even close to 1350 degrees, but the mineral composition of kaolin is different, around the mining kaolin component is so different, so that a lot of kaolin with today's porcelain stone in the data has been very close to the standardized production and the western industrialization under the background of different kaolin most of the China, or in the production of kaolin ore deposit by the way.
The difference between the mines leads to uneven composition and leads to inconsistent quality. The loss of many mud and glazes in China is very important for this reason.
