The present washer, also known as tangle xi, or 'gong-shaped washer', is discussed by Ralph Chait in 'The Eight Prescribed Peachbloom Shapes Bearing K'ang Hsi Marks', Oriental Art, Winter 1957, vol. III, no. 4, pp. 130-137, as one of the eight peachbloom wares for the scholar's desk. 

A similar washer of this type and a complete group of the eight peachbloom wares can be found in the Metropolitan Museum of Art, New York, illustrated in Suzanne Valenstein, A Handbook of Chinese Ceramics, New York, 1989, p. 237.  Another example was sold as part of a set from the Jingguantang Collection at Christie's Hong Kong, 3rd November 1996, lot 557.  This elegant shape also appears during the Kangxi period in a 'claire-de-lune' glaze, such as the brushwasher from the Collection of Paul and Helen Bernat, sold in these rooms, 2nd May 2005, lot 672.
