The present vase belongs to a small group of Kangxi-marked amphorae molded with dragons leaping from crashing waves. However, even within this rare type, this vase stands out as perhaps the only example in which the dragons are painted in underglaze-red against a molded white ground. By contrast, on other amphora vases of this type, both the dragons and the sea are molded, and the vase is covered entirely in celadon glaze. Celadon-glazed versions include an example in the collection of the Palace Museum, Beijing, published in Zhongguo meishu quanji: Gongyi meishu bian, taoci [Complete Collection of Chinese Art: Decorative Arts, Ceramics], vol. 3, Shanghai, pl. 157; one from the Jingguantang Collection, formerly in the collection of the Tsui Museum of Art, published in The Tsui Museum of Art: Chinese Ceramics IV, Qing Dynasty, Hong Kong, 1995, pl. 3, and sold at Christie's Hong Kong, 3rd November 1996, lot 566; one sold in our Hong Kong rooms, 28th November 1979, lot 363; and another sold in the same rooms, 23rd October 2005, lot 368.
