QIANLONG WHEEL-CUT FOUR-CHARACTER MARK WITHIN A DOUBLE SQUARE AND OF THE PERIOD (1736-1795)

Yellow glass vessels are very rare due to their strict restriction for imperial usage. A comparable example similar to the present tripod censer, also bearing a Qianlong mark in double squares, in the Andrew K.F. Lee Collection, is illustrated in Elegance and Radiance, The Art Museum, The Chinese University of Hong Kong, 2000, no. 54. Compare a similar yellow glass tripod censer sold at Christie's Hong Kong, 28 November 2018, lot 2933.
