This was in a lot at auction and I'm not at all familiar with this kind of glass. The bowl is heavy and is 3" high and 5 1/4" top diameter. The top and bottom rims are ground. I'm assuming it's fake? Thanks for your help!
I'd think modern Chinese. If it wasn't "signed" I'd throw a few bucks at it as a pretty bowl. Not worth even spending pennies for a fake.
