Previously sold in Hong Kong, 17 May 1989, lot 466.
The present example appears to be a larger and more elaborate version of the comparable glass pot carved through an amber outer layer from the City Art Gallery, Bristol, included in the Exhibition of Chinese Art, Venice, 1954, Catalogue, no. 915. Compare also the bowl of similar shape decorated with red dragons carved through to an opaque white ground illustrated in Zhongguo Meishu Quanji, vol. 10, p. 146, col. pl. 273. The stylistic treatment of the dragons on the present example is also closely related to those found on a yuhuchunping illustrated in ibid., p. 143, col. pl. 268.
