Ceramics have been produced for over 1800 years in Jingdezhen, China. Emperor Zhenzong decreed that Changnanzhen, as the city was know then, should produce all of the porcelain used by the imperial court during the Jingde Period (1004-1007). The industry continued to develop there during the Song, Yuan, Ming, and Qing Dynasties. Today Jingdezhen 景德镇 is a recognized center of highest quality porcelain production.
