KANGXI/YONGZHENG PERIOD, CIRCA 1700-1735

A very similar crizzled blue glass shallow bowl with similarly lobed sides, also dated Kangxi/Yongzheng period, is illustrated in the exhibition catalogue, Elegance and Radiance: Grandeur in Qing Glass. The Andrew K.F. Lee Collection, The Art Museum, The Chinese University of Hong Kong, 2000, pp. 86-87, no. 3. The entry notes that the "particular blue hue," the texture, and the crizzling indicate that the bowl "was manufactured at the Palace Workshops for court use." Another very similar blue glass shallow bowl, dated to the Kangxi period, in the Asian Art Museum, San Francisco, The Avery Brundage Collection, is illustrated by C. Brown and D. Rabiner in the exhibition catalogue, Clear as Crystal, Red as Flame, China Institute, New York, 1990, p. 45, no. 7, where a green glass example in the Corning Museum of Glass is also illustrated, no. 8. Two other similar bowls, one blue in the City Art Gallery, Bristol, the other green in the Royal Scottish Museum, Edinburgh, with Yongzheng marks, were included in the Oriental Ceramic Society exhibition, The Arts of the Ch'ing Dynasty, London, 1964, pl. 103, nos. 314 and 315, respectively.
Crizzling is a deterioration of the glass due to an excess amount of alkali in the preparation, and is seen in glass of the Kangxi and early Yongzheng periods.
