During the Western Zhou Dynasty, its colored glaze technology was relatively primitive, mostly in the form of simple beads and tubes. As the demand for natural jade increased during the Spring and Autumn Period and the Warring States Period, colored glaze became popular as a substitute for jade and promoted innovation in it. Beginning in the Han Dynasty, colored glaze entered a period of rapid development. Craftsmen began to master the art of making colored glaze using lead as a co-solvent. Colored glaze was no longer just a substitute for jade, but colored glaze vessels began to appear. During the Wei, Jin, Southern and Northern Dynasties, the technology of making calcium sodium glaze was introduced from the Western Regions, and the first large-scale colored glaze factory appeared in Pingcheng, the capital of the Northern Wei Dynasty. During the Sui and Tang Dynasties, cultural exchanges between various ethnic groups were frequent, and glassware with both Persian and Central Plains characteristics appeared.
Modern colored glaze combines ancient glaze methods to improve the process. The current situation is molding, the material has richer colors, and the cost is suitable for mass consumption. It is widely used in jewelry wearing, clothing matching, home decoration, etc.
