They all glow wonderfully green under U.V,despite their whiteness!
All of the white cased items with applied flowers & the like that I've got in my collection have uranium.It's odd that it was used to make white glass, but I'm not complaining!
In fact, when I first got a black light a few years ago, I was happily shining it around the house at all the obvious pieces of vaseline glass- & was very surprised to see all the white things that turned green! :shock:
I tried it on my glass button collection later & found that a lot of rather plain looking white buttons have a double life as glowing green ones!
Hours of fun! :lol:
