Please Help ID: Pressed Glass Rounds Insulator Cups?

Good Evening Antiquers,
Does anyone know what these are?
They look like impressed or stamped blown glass rounds
They measure just over 2" in diameter and stand about 1.5" tall.
No marks or signatures.
I thought they could be finals or pulls, but I can't tell.
There is no way to insert hardware and nothing seems to fit.
Someone said they could be salt dishes but that doesn't seem correct either.
When I got them, it looked like there was a wax residue in them.
Could these be molds?

Thank you kindly for your input and stay healthy everyone.

 

Did you forget your photographs?

<------Wondering if they could be Butter molds. Never seen any like that (mostly metal ones).

 

They kinda look like piano insulators.

 

Thank you very much, I was thinking butter or candy molds although they seem a little too "fancy" for that. Thanks again!

 

Thank you! I'm going to do some looking in this direction. I did a quick search and they look really similar. I saw some Victorian glass furniture castor cups that also looked close to these with similar dimensions. Thanks again for the suggestion!

 

They look like cigarette snuffers to me - what size is the center hole?

I agree.

 

They look like Scandinavian modern candle holders for taper candles. Kosta Boda, Orrefors, etc.
