Going through my aunt’s collection I found everything from Depression Class to Uranium Glass. Having our own Geiger counter we had to give it a try to see how it came out.
Uranium glass, also known as Vaseline glass, is a collectible favorite among antique enthusiasts and science buffs alike. Characterized by its vibrant green or yellow hue, uranium glass contains trace amounts of uranium oxide, which gives it its unique glow under ultraviolet (UV) light. If you’re on the hunt for uranium glass, two tools can help you identify it: a Geiger counter and a UV light. Here’s how these tools compare and what you should know before you set out on your search.

How It Works:
A UV light, often referred to as a blacklight, causes uranium glass to fluoresce with a bright green or yellow glow. This happens because the UV light excites the electrons in the…
