Gilded porcelain vessels are rare and may have been made in imitation of gold or gilt-metal vessels. A gilded porcelain stem cup and cover of Qianlong date is illustrated by J. Ayers, Chinese Ceramics in the Baur Collection, vol. 2, Geneva, 1999, no. 336, where two others in Japanese collections are cited. Two other pieces, a 'gold-glazed' cup and a figure of a buffalo in the Percival David Collection, are included, but not illustrated, by M. Medley in the catalogue, Ming and Ch'ing Monochrome, London, 1973, Section 6, nos. 598 and 599.
