Those who burn kilns are called kiln households, and those who make blanks are called blank households.

In the past, the two became one, and the Ming Dynasty began to separate.

This is the social division of labor, and professional people do professional things.

Now Jingdezhen is also in this format. Those who burn kilns do not make porcelain, and those who make porcelain do not burn kilns. Only a few large workshops have their own kilns, which are often sold to small workshops. In the past, the owner of the kiln just paid the bill, hired a pile owner to be fully responsible for daily production, and then hired people to purchase wood and so on.
