Ding ware, Ting ware (Chinese: 定瓷; pinyin: DìngcÃ) or Dingyao are Chinese ceramics, mostly porcelain, that were produced in the prefecture of Dingzhou (formerly romanized as "Ting-chou") in Hebei in northern China. The main kilns were at Jiancicun or Jianci in Quyang County. They were produced between the Tang and Yuan dynasties of imperial China, though their finest period was in the 11th century, under the Northern Song. The kilns "were in almost constant operation from the early eighth until the mid-fourteenth century."
The most characteristic wares are thin porcelains with a white or greyish body and a nearly transparent white-tinted glaze, though they are classed as stoneware by some. Chemical analysis has shown that they were often made entirely of a kaolinitic clay without any petuntse or "porcelain stone". They are mostly decorated with uncoloured designs that are incised or in very shallow relief.
