The production methods of ceramic tableware are mainly divided into two types: overglaze color and underglaze color:

Overglaze colored ceramics are made by pasting colored paper with pigments on the glaze surface or directly painting the pigments on the surface of the product, and then firing it at high temperature. Since the temperature is not high enough to melt the glaze, the pattern cannot sink into the glaze, and there is a noticeable bump when touching it.

All the color decoration of underglaze colored ceramics is done on the porcelain blank, formed in one time at high temperature, and the glaze layer covers the picture.
