Ru Kiln

Ru kiln, Pinyin Ru yao, or Wade-Giles Ju yao, kiln known for creating highly prized Chinese stoneware. The Ru kiln produced ware for a short period during the years when Northern Song emperors Zhezong (1085–1110) and Huizong (1110–1125) ruled.

No more than 60 intact pieces from the kiln were known before the discovery in 1986 of the original kiln site, which is in the village of Qingliangsi, in Baofeng county, Henan province. This site has yielded at least 37 more examples (22 of which are intact). The undecorated bluish or greenish gray glaze of Ru wares was cloudy and opaque, often with a slight lavender tinge and a fine, irregular network of cracks. The glaze typically covered a gray stoneware body that had a simple, elegant shape.
