How are the blue stripes of blue and white porcelain formed?

The blue stripes of blue and white porcelain are formed by a special decorative technique.

In the process of making blue-and-white porcelain, the white porcelain blank is first fired and shaped, and then a special blue pigment is coated on the surface of the porcelain, which is made by grinding the ore containing cobalt oxide.

Next, the artists carefully applied the blue pigment to the porcelain surface with a fine brush or a thin tube pen to form various patterns and patterns. This process requires great skill and patience, because once smeared, it can't be repaired.

Finally, the porcelain coated with blue pigment is fired in a high temperature kiln. At high temperature, the blue pigment will fuse with the glaze on the surface of porcelain to form durable blue stripes.

This decorative technique makes blue-and-white porcelain have unique artistic charm and become one of the representatives of traditional ceramics in China.
