Chinese cloisonne, whose history can date back to over 500 years ago, is well-known Chinese traditional enamelware. It is actually called the "Blue of Jingtai" as blue is the dominant color adopted for enameling, and celestial cloisonne became prevalent during the reign of Jingtai (1450--1456) in the China Ming dynasty. Owing to the brilliant color and splendid designs, cloisonne has been highly appraised.
Regarding the making of cloisonne, it involves quite elaborate and complicated processes: base-hammering, soldering, enamel-filling, enamel firing, polishing and gilding.
