Uranium Glass

Uranium glass is made by adding small amounts of uranium oxide added to the glass mixture, usually the purpose is to give a strong green or yellow colour. Vaseline glass is glassware that is made with uranium content to give a pale yellow green colour similar to that of petroleum jelly. Uranium glass can be detected with a geiger counter, or an ultraviolet (UV) light. Uranium glass glows bright green under UV light, and this fact has led to uranium glass becoming popular with collectors.
