Uranium Glass
Uranium Glass — What Is It?
Uranium glass is a type of glass with uranium added during manufacture, giving it a desirable green or yellowish hue. The practice began in the early 19th century and was especially popular during the Victorian period (1837–1901). Glassmakers found that adding small amounts of uranium oxide created beautiful, vibrant colours — not yet knowing its hidden secret, as ultraviolet electric globes had not yet been invented.
Production continued into the 20th century, pausing during and after World War II when uranium was diverted to nuclear research. It resumed in the 1950s–60s before becoming less common again. The glass glows brilliantly under UV light — the uranium atoms react and emit a vivid greenish light. A cabinet full of endlessly varied Victorian uranium glass vessels is like a science-fiction alien planet: mesmerising.
Despite containing uranium, uranium glass is not dangerous. The amount used is typically less than 2%, emitting only trace radiation — far too low to be harmful. As long as it is not ingested or ground into dust, collecting and handling it is entirely safe.
