Note: Jade barbed-rim wares in this style are very rare. Examples of similar barbed-rim dishes in metal include a silver dish that was excavated in an 8th century tomb in Inner Mongolia, and another silver dish that was discovered in a Yuan dynasty tomb near Shanghai, see James C.S. Lin, Chinese Jades from the Neolithic period to the Twentieth Century, London, 2009, pp. 66-67. A strikingly similar mottled gray jade barbed-rim bowl of this type in the collection of the Fitzwilliam Museum, Cambridge has been published in J. P. Palmer, Jade, London, 1967, pl. 19, and in op. cit., cat. no. 57.
