Dong Qichang
Generally speaking, Tianqi porcelain was one variety of porcelain among various styles of the Jingdezhen unofficial kilns from a time of production breakdown of the official kilns at the death of the Wanli Emperor in 1620 to a time of reorganization in 1683 during the reign of the Kangxi Emperor in the Qing Dynasty. The Tianqi ware, and other associated wares, display a refreshing spontaneity of design that makes them unique in Chinese ceramic history. The influence of the master landscape artist Dong Qichang (董其昌) (1555-1636) can be discerned in the use of a dark and light color contrast.
