Porcelain Makers Marks and Information. Kangxi transitional porcelain was manufactured at China’s principle ceramic production area of Jingdezhen until 1683 when the production of “official ware” was resumed.
The Manchu regime was established in 1644. For those many intervening years a variety of porcelain wares were created in private kilns for domestic use and export to client markets such as Japan. Prior to the reinstatement of the Imperial Kilns the private use of the dynastic reign name on ceramics was officially forbidden in the 16th year of the reign of the Kangxi Emperor in the Qing Dynasty (around 1677). Previously in the years of the Wanli Emperor (1573–1619) of the Ming Dynasty, ceramics under government sponsorship slowly degenerated in quality until production itself was abandoned.
