Looks like something out of the 1960s -'70s if its an ash tray.

I've seen things like this used as floor protectors under furniture & piano legs

I go with the floor protector idea. They were used to keep the metal caster wheels from digging into the softer wooden floors.

Piano leg insulator. Protected against vibrations or something like that. For sound quality.

I have a collection of glass floor protectors, but none are larger than about 2" diameter. Never seen one that big!
