Previously sold at Sotheby's Hong Kong, 14 November 1983, lot 142.
Compare with two identical Kangxi-marked dishes, the first illustrated in Chinese Porcelain, The S.C. Ko Tianminlou Collection, Hong Kong, 1987, Part I, pl. 144; another from the Koger Collection, illustrated by J. Ayers, Chinese Ceramics - the Koger Collection, 1985, p. 172, pl. 144. It has been suggested that this vibrant purple glaze was an innovation of the late Kangxi period, and the Koger dish was 'part of an Imperial dragon service, continuing a style instituted under the Ming', op. cit., 1985, p. 172.
