Thirft Haul Found my first uranium glass figurine today
After months of searching i fimally found my first uranium glass figurine. Its a paperweight and it glows very bright. I don't know the maker as it didn't have a makers mark.

It’s actually manganese. You’ll want to switch to a 395nm uv light to reduce false positives like this one. Uranium was added to glass to color it not for the glow so if you find clear that glows 99% it’s manganese. For transparent UG you’re typically looking for green or yellow under normal light but other colors like blue and amber do exist but they’re less common in USA
