These glasses are unique and interesting. The glass is “Shannon Crystal” as described in the enclosed information. The glass is not as fine as I anticipated but not too thick, either. One thing I was surprised to learn is that the soapstone base is not attached to the glass. The glass rests on top of it which is interesting. The enclosed information states the soapstone base can be placed in the freezer to keep beverages chilled.. Anonymous. Thu Nov 03 2022
