This bottle is an early example of a ruby-red bottle produced at the Palace Workshops. The shape is extremely unusual, incorporating the flat or dished central panels which may have acted as integral snuff dishes. See one from the Bloch Collection illustrated by Moss, Graham, Tsang in A Treasury of Chinese Snuff Bottles, Vol. 5, Glass, no. 792, also without a foot but with continuous flattened narrow side panels. The shape is probably derived from European pocket-watches, which were imported into the Palace in the late-seventeenth and early-eighteenth centuries.
