The fundamental difference between official kiln and private kiln

In the Tang Dynasty, official kilns appeared. At that time, official kilns referred to official factories and tributes. They are produced in the form of official supervision and civilian burning, and porcelain is burned. One in a thousand pays tribute to the ruling class. The selected porcelain is called official kiln or tribute porcelain. Folk kilns are relative to official kilns. Broadly speaking, they are run by unofficial government and mainly produce commercial porcelain for ordinary people.

The difference between folk kilns and official kilns lies in:

The official kiln was built and burned by the government, and all actions were based on serving the palace. Official kilns can also forcibly occupy high-quality porcelain clay and raw materials, work for skilled craftsmen all over the world, and control glaze color and porcelain-making technology. It is forbidden for people to imitate, regardless of the production cost, and the production process is exquisite, which represents the highest level of porcelain-making technology in China at that time. Every operation link strives for perfection.

Folk kilns mainly serve ordinary people, choose suitable places according to different market needs, and produce and sell all kinds of porcelain by themselves. At present, most of the kiln sites found in Longquan are folk kilns, which are highly subjective and arbitrary in shape, structure, materials and so on.
