How did the watch case on China burn?

The method of firing porcelain:

1, the patterns on the original pottery are generally drawn directly on the pottery after grinding mineral raw materials and adding water. Usually remove the glaze, and you can watch pictures of Majiayao culture and Yangshao culture.

2. Most of the patterns before Yuan Dynasty are the same as the original porcelain, but they are mostly monochrome. Except Cizhou Kiln and Changsha Kiln, underglaze color paintings are used. First, burn the blank, then paint, and then burn a layer of glass glaze.

3. Mature blue and white porcelain appeared in Yuan Dynasty. It is made by first making a blank, then coating cobalt oxide on the blank, adding a layer of glass glaze, and then firing, so the blue and white porcelain we see appears.
