A larger, unmarked flambé vase of similar shape is illustrated by J. Ayers in The Baur Collection - Chinese Ceramics, vol. 3, Geneva, 1972, no. A 289, where he notes that "kiln transmutations (yao pien), liable to occur during the firing of the copper-red glazes were first exploited during the reign of Yong Cheng, when attempts to imitate the effects of ancient Chun wares were made; when in some cases - as here - the process was assisted by adding splashes of cobalt". Daoguang-marked flambé-glazed vases of this shape appear to be quite rare. For earlier examples of this type, compare a Yongzheng-marked flambé-glazed example of similar archaistic shape and height (8 5/8 in.) sold at Christie's New York, 21 September 2004, lot 316; and a Qianlong-marked example in the Exhibition of Chinese and Other Far Eastern Art Assembled by Yamanaka & Co., New York, 1943, no. 915. See, also, the very similar Daoguang-marked vase sold at Christie's London, 7 November 2006, lot 212.
