Chemical composition is the critical factor determining what crystal pattern it would form. It most commonly made of frit, silica, and iron/zinc oxide. Crystalline glaze exists a long time since Sung Dynasty. In the early days, it belongs to iron crystal, which is known as black glaze, such as Yuteki, Rabbit-fur streaks and Tenmoku glaze.

Gradually, crystalline glaze had been evolving into different types, such as tea-dust, eel-yellow and crab-green glaze in Ching Dynasty. Since people had a lack of knowledge of chemical changes, those glazes mostly are named after their patterns and physical appearance.
