A holy water vase, or kundika, this vessel is likely to have been made for Buddhist ritual use. A similar vessel, unfortunately damaged at the neck, decorated in underglaze blue and believed to be from the Xuande through Zhengtong periods, was discovered in a tomb in Jingdezhen. See Jingdezhen minjian qinghua ciqi (Zhongguo taoci quanji, vol. 19), 1983, pl. 12.
Also compare a vase of Zhengde date in the Percival David Foundation with the same high-shouldered body raised on a spreading foot and with a tall neck which flares at the mouth, but with a pair of handles suspending loose rings instead of the flanged knop, illustrated by Daisy Lion-Goldschmidt, Ming Porcelain, pl. 105, p. 132
The use of green overglaze enamel without any other painted ornament occurs mainly on Ming porcelain of the Hongzhi and Zhengde periods. A small jar decorated with dragons in the same color of green enamel also without the design incised first but with penciled black outlines, and with a green enameled Jiajing mark within a double circle, is illustrated by John Ayers, Chinese Ceramics, The Koger Collection, pl. 61
