In fact, the technology of cloisonne and enamel appeared very early in China. The technology of pinching silk existed in the Warring States Period. In the tombs of the Han Dynasty, there is a kind of exquisite decoration, such as round carving, inlay, drawing and beading. In the tombs of the Eastern Han Dynasty in Wulipai, Changsha, Hunan Province, in the early tombs of the Eastern Han Dynasty in the suburbs of Guangzhou, and in the tombs of the Wei, Jin, Southern and Northern Dynasties, there were all cloisonne beads. Therefore, the process of beading with silk is very old and has been circulated for a long time.
As for the enamel craft, in the Spring and Autumn Period, Goujian's hilt was inlaid with enamel glaze, and the bronze pots in the Han tombs in Mancheng were also decorated with enamel.
However, in a long historical period, enamel technology has not formed a scale and has not been well developed.
