Note: This type of brush washer is described as being of 'gong' shape, or tangluoxi, as it has a very compressed body. It belongs to a group of vessels referred to as the badama, 'Eight Great Numbers'. This group was previously thought to comprise a total of eight differing shapes. John Ayers identified a possible ninth form of the Ba Da Ma by pointing out the existence of two slightly different globular water pots. The first is termed as a Pingguo zun, 'apple jar' modelled with a gently inward curving mouth rim; and the other with a raised, low, neck (similar to a stalk) that maybe referred to as a Shiliu zun, or 'Pomegranate jar'. See, J. Ayers, 'The Peachbloom Wares of the of the Kangxi Period (1662-1722), Transactions of the Oriental Ceramic Society, vol. 64, 1999-2000, p.49.

Many of the world's great museums have published similar examples of brush washers, including the Metropolitan Museum of Art, The Palace Museum, Beijing and the Sir Percival David Collection at the British Museum, London. The brush washer in the Metropolitan Museum is illustrated with a group of peachbloom-glazed vessels made for the scholar's table, including a beehive water pot, illustrated by S. Valenstein, A Handbook of Chinese Ceramics, New York, 1989, rev. ed., p. 237, no. 236. Compare with examples of Kangxi-marked brush washers of this type sold at Christie's New York, 15 September 2009, lot 445, and 16-17 September 2010, lot 1403.
