Wanya Xuan, the Studio of Refined Amusement, is not a recorded studio name, although it appears on a number of bottles of different colors but of similar shape where the mark is sometimes placed in this unusual position on one narrow side. Other examples of this type of bottle include another from the J&J Collection, made from a streaky yellowish green glass, illustrated by Moss et. al., The Art of the Chinese Snuff Bottle, vol. 2, no. 343; a turquoise-blue version illustrated by Hugh Moss, Snuff Bottles of China, p. 116, no. 260; a yellow example illustrated in JICSBS, June 1977, p. 9, no. 18; one of turquoise-green glass, illustrated by Joseph Silver, Chinese Snuff Bottles from the Collection of Joseph Baruch Silver, p. 12, no. 12; another yellow bottle illustrated by Marian Swayze Mayer, Glass Snuff Bottles of China at Steuben Glass, no. 61, and no. 124 for one in opaque green.

This mark could either be the studio name of the bottle owner who favored this shape and the different colors of glass, or it could be the identifying device of a particular workshop.

The present bottle is probably the most elegant of the group, because it is rather thinner and longer than the standard shape. The high degree of translucence also increases the sense of elegant thinness of this example.
