I've seen it in the earliest Vitro marbles that I know of. Some helmets will glow, for instance.
It would have become unavailable during WWII and then for about 15 years after that.
Some cat's eyes have uranium glow. Not sure about the non-cat's eye types from the 60's and beyond since it has been a long time since I have checked, but I bet some do.
I don't know if it made it all the way to 1990. I guess I could take a blacklight to my Anacortes bag .... BRB.
Well, that was a dud. I think I see a little bit of green glow. But not even enough to be sure. So my small sample of the latest era Vitros is not helpful in answering the question.
