Just purchased this from a second-hand shop, not even sure what it is. A few details:
3 1/2" tall
4 1/2" Diameter across the top
weighs 354g
is nonmagnetic
rings bell-like if struck
ice placed in it melts quickly - as if on a hotplate.
blue-black tarnish
So, it certainly seems to be high-content silver in terms of material; but it has no markings, either hallmark or decoration, and so I have no idea exactly what it is, much less from when or where. Any assistance on this would be greatly appreciated. Picture is attached below.
