There's also an awful lot of American yellow uranium glass (vaseline)
There were, but the consensus from EAPG group I frequent was that they did not think it was American. But since it has gone around the world and the general consensus was "not likely us", it very well could be American. I like researching glass, I think I got it from my dad (he helped write a book) and it just interests me to no end. But it also gnaws on me when one goes unknown.

I just need to get this picture in front of the right person at the right time. Until that happens, the saga continues.
