Glaze is a continuous vitreous layer attached to the surface of ceramic body, or a mixed layer of glass and crystal. The glaze may be produced by calcareous stone and charcoal ash used in ancient barrier stone cooking, or by the aesthetic texture of shell surface, consciously using shell powder as raw material.

There are many kinds of glaze, according to body type, there are porcelain glaze, pottery glaze and Firestone glaze; according to firing temperature, the glaze below 1100 C is called low-temperature glaze, the glaze between 1100 C and 1250 C is medium-temperature glaze, and the glaze above 1250 C is high-temperature glaze; according to glaze surface characteristics, white glaze is probably people's favorite for silver. Colored glaze is welcomed by people because of its colorful, crystal glaze pattern is changeable and beautiful, kiln varying glaze is dazzling and beautiful, cracked glaze is clear, simple, elegant and unique.

The so-called pottery and ceramics refer to products made from plasticity ceramic clay and porcelain stone ore as matrix, feldspar and quartz as raw materials, and through moulding, drying and firing, mainly including daily use, art, and architectural pottery. Archaeological discoveries have proved that the Chinese invented pottery as early as the Neolithic Age (about 8000 BC). Agricultural production in the late primitive society enabled Chinese ancestors to live a relatively fixed life, objectively demanding pottery. In order to improve the convenience of life and the quality of life, pottery was gradually made by firing clay.
