One of the advantages of a colorless ground is that each overlay appears in its true color, as seen on the present example. The rare combination of colors on this bottle is enhanced by the impeccable carving and well-composed design. See Moss, Graham and Tsang, A Treasury of Chinese Snuff Bottles, Vol. 5, Glass, nos. 985-92, for a discussion of this group of multi-color overlay snuff bottles. The subject, style and some of the colors link this to an example carved with lotus illustrated by M. Hughes, The Blair Bequest. Chinese Snuff Bottles from the Princeton University Art Museum, nos. 189 and 191. The classic examples of this group of bottles consist of a variety of colors spread around the bottle linked by a common color, here, by the green overlay stems and foliage.
