I purchased this in either England or France. I was told it was uranium glass, also known as Vaseline glass, but I didn't check it with a black light. The color looks like opaline glass, so I've corrected the price to reflect that. The shape is unique, with a lovely, rounded top! I don't see any noticeable chips. I believe the bubbles and dark spots are from the manufacturing process. Thank you very much! ♡♡♡
