though obviously not impossible, I'd suggest that would be exceptional - I used to collect a lot of this stuff late 1920s onward, and never once found uranium in Stuart drinking glasses, bowls or whatever shape - plenty of items in green glass, but never got a reaction with the u.v. torch.
I'd be really keen to see anything from Stuart, from that period, in uranium. It occurred to me often to wonder why Stuart didn't seem to do uranium green, when so many contemporaries did.
