Uranium Glass

Uranium glass, also called vaseline glass, is glass that contains a little bit of uranium.

It's main quality is that it glows green under blacklight. It's pretty impressive.

Despite containing uranium, it's not that radioactive. It is a little radioactive, but not enough to matter. I hope.

This is not radium, which is an element that glows. It's uranium, and it glows only when you shine a blacklight/uv light on it.

I have this ashtray made of uranium glass for sale:
