YONGZHENG SIX-CHARACTER SEAL MARK AND OF THE PERIOD (1723-1735)

A small group of Yongzheng-marked 'ribbed' vases are recorded, such as two Ge-type glazed vases of the same size, one from the Greenwald Collection, sold at Christie's Hong Kong, 1 December 2010, lot 2823, the other from the Carl Kempe Collection, sold at Sotheby's Paris, 12 June 2008, lot 102. A slightly larger vase of Guan-type glaze (26.2 cm. high) is illustrated by J. Ayers, Chinese Ceramics in the Baur Collection, Geneva, 1999, no. p. 163, no. 269 (A335).

Compare also the Song prototypes from which the Qing examples imitate, illustrated in Kuan Ware of the Sung Dynasty, Porcelain of the National Palace Museum, Taipei, CAFA, 1963, pls. 12 and 13; the present vase is of the same height as the two Song examples.
