Cloisonne, also known as filigree enamel work, is perhaps the most famous of all traditional Chinese metal craftworks, with Beijing as the producing center. The making of cloisonné involves a complex enameling technique – from soldering to a copper surface delicate metal strips bent to the outline of a design, to filling the resulting cellular spaces with vitreous enamel paste, before the object is fired, ground smooth and finely polished. Cloisonne is called “jingtai-lan” because its popularity reached a peak during the Jingtai reign (1450-1457) of the Ming Dynasty. The Chinese cloisonné comes in such forms as vases, bowl, plates, table lamps, and cups used as prizes.
