Vaseline Glass?

Is there a way to tell if something is Vaseline glass without a black light?

That green glass is Uranium glass. I have run across tons of that. Vaseline glass is yellow colored depression glass. Made with uranium oxides. Vaseline glass is a subset of uranium glass that has uranium in it, but that is only yellow in color. True depression glass should have tons of tiny bubbles in it. Best to use a uv light.

Other than a blacklight, a Geiger counter. Just the other day I checked how hot my Vaseline glass is, and the hottest piece is about 6 times over background radiation. The weaker pieces are about 3 times over background radiation.

The background radiation at my place is about 13 counts per minute (CPM), because of the elevation of my property. It's usually lower at sea level.

Wow, that's thinking outside the UV box so to speak. Very intelligent problem solving.

The first three are depression pressed glass, not Vaseline glass.

The three greener pieces have added iron oxide, which gives them the "Vaseline" green color, a 'common' name for the glass, although not technically correct.

I would love to find one of the pieces made with 25% uranium. That would be hot. o_O:p
