What is the purpose of this footed glassware with a large round bowl and a decorative handle? I inherited a very large collection of glassware, most of it I recognised, some very esoteric (specific vessels for specific kinds of alcohol etc). I've been able to identify and understand the intended purpose of every piece except for a set of four unusual glass cups/bowls.



For perspective: A tennis ball would fit snugly inside.

The small glass spiral on the side does not feel strong enough to be used as a handle even when the vessel is empty so I was wondering if it was perhaps intended to hold some kind of spoon or something. Maybe entirely decorative?

Any information on what this is or what it's for would be greatly appreciated.
I think it's an artistically stylized ale glass.
