Porcelain Jingdezhen may have produced pottery as early as the sixth century CE, though it is named after the reign name of Emperor Zhenzong, in whose reign it became a major kiln site, around 1004. By the 14th century it had become the largest centre of production of Chinese porcelain, which it has remained, increasing its dominance in subsequent centuries. For several centuries, almost all top quality Chinese porcelain has come from the town. From the Ming period onwards, official kilns in Jingdezhen were controlled by the emperor, making "imperial porcelain" in large quantity for the court and the emperor to give as gifts. Although apparently an unpromising location for potteries, being a remote town in a hilly region, Jingdezhen is close to the best quality deposits of petuntse, or porcelain stone, in China, as well as being surrounded by forests, mostly of pine, providing wood for the kilns. It also has a river leading to river systems flowing north and south, facilitating transport of fragile wares. The imperial kilns were in the centre of the city at Zhushan (Pearl Hill), with many other kilns four kilometres away at Hutian. It has produced a great variety of pottery and porcelain, for the Chinese market and as Chinese export porcelain, but its best-known high quality porcelain wares have been successively Qingbai ware in the Song and Yuan dynasties, blue and white porcelain from the 1330s, and the "famille rose" and other "famille" colours under the Qing dynasty. The town continues to produce cheaper tablewares in great quantity, as well as more expensive decorative pieces. During the Cultural Revolution, Jingdezhen produced a large number of porcelain Mao badges and statues of a seated Mao Zedong. Jingdezhen porcelain has fetched record prices at auctions, with a blue and white porcelain jar produced during the Yuan dynasty auctioning for $27.7 million in London in 2005, and a porcelain cup produced during the Ming dynasty auctioning for $36.3 million in 2014. Economy Jingdezhen serves as an important industrial and commercial base in Jiangxi Province. In 2018, Jingdezhen achieved a GDP of 92.611 billion yuan. Of this, 6.62% of the city's GDP came from its primary sector, 44.22% came from its secondary sector, and the remaining 49.16% came from its tertiary sector.
