Enamel painting technology of metal tire originated from France in the17th century. During the reign of Kangxi in Qing Dynasty, this handicraft was brought to the official court of China by missionaries.

Kangxi set up enamel color in the interior office and copied the enamel color technology. The imported enamel materials are used for trial firing on carcasses with different textures, such as copper, glass, porcelain and purple sand. The earliest product was painted enamel on copper tire, and Falang colored porcelain creatively applied the enamel color previously decorated on copper tire to porcelain, which is called painted enamel on porcelain tire.
