清康熙 天藍釉漢壺尊 《大清康熙年製》款

the pear-shaped body rising from a short straight foot to a tall slightly tapering neck with everted rim, covered overall with a soft pale blue glaze thinning to white at the rim, the white-glazed base inscribed with an underglaze-blue six-character reign mark

The rim has some scattered kiln grits with a tiny patch of dirt probably removed, revealing the white core. Apart from some glaze crackles with the longest measuring 1.3 cm near the bottom of the vase, the overall condition is good. The brilliant soft-blue glaze is evenly applied except for a 1 cm area on the lower part of the body. There are also a few minor nicks to the unglazed foot.

Vessels of this elegant form and glaze colour, known as tian lan ('sky blue'), are rare; see a closely related example of slightly larger proportions in the Palace Museum, Beijing, illustrated in The Complete Collection of Treasures of the Palace Museum. Monochrome Porcelain, Hong Kong, 1999, pl. 88. Compare also a slightly larger clair-de-lune glazed vase of similar form, but with a longer neck and more compressed body, in the Baur Collection, illustrated in John Ayers, Chinese Ceramics in the Baur Collection, vol. 2, Geneva, 1999, pl. 177; and another from the collection of David A. Berg, sold at Christie's New York, 21st September 2000, lot 373, and again in these rooms, 11th April 2008, lot 2992.

For the Song prototype of this shape compare a celadon vase in the Metropolitan Museum, New York, published in Oriental Ceramics. The World's Great Collections, vol. 12, Tokyo, 1977, pl. 52.
