    Looks like it’s being lit with a black light

      I don’t know if this is real, but real uranium glass just glows (although it is not this brightly unless the light is fairly low). I have a tiny bit on a keychain somewhere.

      I used to keep it in my pocket as my normal keychain and joke that it would stop me from having kids.

      It apparently didn’t.

        Not quite,

        Radioactive substances don’t actually glow visibly themselves…

        Uranium glass fluoresces under UV, and tritium vials and radium paint contain phosphers that convert radiation to visible light.

          Well all I know is I could see my keychain glow in the dark and it claimed to be uranium.

              I guess whatever is in it isn’t uranium then. 🤷
