of circular section, the shallow straight sides resting on three short cabriole legs, The outer wall is covered in raised continuous floral scroll. the base centered with a six-character seal mark in underglaze blue encircled by nine small spur marks near the edge A former collectors label on the underside reads: "Chinese Celadon tripod Brush washer 1723-1735 Zheng". The present washer is a fine example of the technical perfection achieved by craftsmen working at the imperial kilns in Jingdezhen during the Yongzheng period. As with many Yongzheng and Qianlong monochrome wares, this vessel is a reinterpretation of an archaic bronze lian form which was first developed by Song craftsmen. Monochrome vessels such as the present appear to be the product of Tang Ying (1682-1756), the Superintendent of the Imperial Kilns in Jingdezhen, who reintroduced simplicity of form and the absence of decoration as the new stylistic trends following research into celebrated Song wares such as Guan, Ge, Longquan celadon and Ru.
