The Xing kilns in Hebei province were best known for the production of tea bowls, dishes and bowl stands, and larger vessels, such as ewers, are very rare. Compare a Dingyao ewer, dated to the Tang dynasty, of similar form, with a similar spout but with a phoenix-head cover, illustrated by Bai Zhang, ed., Complete Collection of Ceramic Art Unearthed in China, 2008, Hebei, no. 34. Another Dingyao ewer, dated to the Five Dynasties period, with a spout also of similar simplified phoenix-head shape, is illustrated ibid., no. 77.
The result of Oxford Authentication Ltd. thermoluminescence test no.666g67z is consistent with the dating of this lot.
