Stoneware large bowl with Bluish Celadon Glaze, Northern Song Dynasty, 11th-12th Century, d.19.5cm. Gift of SUMITOMO Group, the ATAKA Collection. Acc. No. 10692 © 2009 The Museum of Oriental Ceramics, Osaka
This is a large bowl with a mouth that flares out. It is covered with the opaque blue glaze unique to Jun ware. Around the rim the glaze is thin, and it has turned a yellowish brown color. The glaze has pooled at the bottom of the bowl, and the entire base is left unglazed. Jun ware is one of the famed kilns of the Song dynasty, and is thought to have been produced in Junzhou; such a place name, however, did not exist in the Song dynasty, but appeared in the Jin dynasty. The origin of this ware is thought to be related to the white opaque glaze of Black glazed ware with white spots which was fired at the Lushan-Duandian kilns in the Tang dynasty. Excavations have confirmed that this ware was fired at Juntai and Linru in Henan Province. Jun ware style shards have also been excavated at the Ru kiln site in Baofen-xian, drawing attention to the relationship between the two wares.
