Cloisonne, with a history dating back over 500 years, is well-known traditional enamelware. It is typically called the "Blue of Jingtai" as blue is the dominant color adopted for enameling and Cloisonne became prevalent during the reign of Jingtai (1450--1456) in the Ming Dynasty. Owing to its brilliant colors and splendid designs, Cloisonne has been highly appraised both in China and abroad. The making of Cloisonne involves quite elaborate and complicated processes: base-hammering, soldering, enamel-filling, enamel firing, polishing and gilding. Cloisonne items are still widely in circulation today, with newer pieces being made every day, and antique cloisonne items going for high amounts at auctions around the world.
