Someone donated an ash tray that contains uranium. Green glass, glows in the dark.

When the boss showed it to me, without thinking I said "I have a Geiger counter at home."
(which I do)

Without skipping a beat, she looks me in the eye and says "Of course you do."
She knows me.

Resulting in a beautiful green glow. Your Geiger counter will find the piece to be no danger to the public, emitting safe amounts of radiation.

I learned that Fenton yellow custard glass glows green under a black light, too. One of my grand kids liked the effect, not sure if they will collect, but if they do, I have several pieces of uranium glass, in case they want it.

Uranium would give a nice orange glaze. Most of us stayed away from it but our professor often used it.

We would make up 3 gallon buckets of glaze, throw in formaldehyde and stir it with our arms. Those were the days?
