CHINE, DYNASTIE QING, MARQUE A SIX CARACTERES EN CACHET EN BLEU SOUS COUVERTE ET EPOQUE DAOGUANG (1821-1850)

Bowls with this decoration appear to be based on Kangxi prototypes, such as the example found in the Qing Court collection, illustrated in The Complete Collection of Treasures of the Palace Museum - Porcelains in Polychrome and Contrasting Colours, Hong Kong, 1999, p. 216, no. 197. It is interesting to note, however, that the Kangxi examples tend to have more rounded sides when compared to their Daoguang counterparts, which tend to have steep, flared sides. For a Daoguang-marked example of the same size, shape and decoration, see G. Avitabile, From the Dragon's Treasure, London, 1987, p. 52, no. 56.
