In the damp and humid climate of parts of China snuff formed into lumps that required crushing on a hard surface. The earliest form of the snuff dish was apparently integral and can be seen on glass bottles with slightly concave or flat circular facets on their main sides (see Moss, Graham and Tsang, A Treasury of Chinese Snuff Bottles, Vol. 5, Glass, no. 786, for an early 18th-century example in turquoise-green glass with similar, framed integral snuff dishes).
The frame of the circular panel on the main sides of this bottle is a standard feature of Palace decoration. Mask handles evolved during the eighteenth century, with the original, functional, circular rings giving ground, gradually, to more elongated rings, better suited to fill the long, narrow sides of the snuff bottle.
