Uranium glass by Ciro Santilli 37 Created 2024-09-15 Updated 2025-07-16
Glass with Uranium added to it to become fluorescent due to Uranium's chemical properties. This is unrelated to Uranium's nuclear properties.
However it was this fluorescence that led Henri Becquerel to discover radioactivity while studying fluorescence, which led him to have Uranium compounds and photographic material in close proximity. I love science I guess.
