Uranium glass is glass which has had uranium , usually in oxide diuranate form, added to a glass mix before melting for colouration. First identified in by German chemist Martin Heinrich Klaproth , uranium was soon being added to decorative glass for its fluorescent effect. Uranium glass was once made into tableware and household items, but fell out of widespread use when the availability of uranium to most industries was sharply curtailed during the Cold War in the s to s. Most such objects are now considered antiques or retro-era collectibles, although there has been a minor revival in art glassware. Otherwise, modern uranium glass is now mainly limited to small objects like beads or marbles as scientific or decorative novelties. The normal colour of uranium glass ranges from yellow to green depending on the oxidation state and concentration of the metal ions, although this may be altered by the addition of other elements as glass colorants. Uranium glass also fluoresces bright green under ultraviolet light. The most common color of uranium glass is pale yellowish-green, which in the s led to the nickname "Vaseline glass", based on a perceived resemblance to the appearance of Vaseline -brand petroleum jelly as formulated at that time. Specialized collectors still define Vaseline glass as transparent or semi-transparent uranium glass in this specific color. Vaseline glass is sometimes used as a synonym for any uranium glass, especially in the United States, but this usage is frowned upon, [7] since Vaseline-brand petroleum jelly was only yellow, not other colors. The term is sometimes applied to other types of glass based on certain aspects of their superficial appearance in normal light, regardless of actual uranium content which requires a blacklight test to verify the characteristic green fluorescence. In the United Kingdom and Australia , the term Vaseline glass can be used to refer to any type of translucent glass.

Canary glass is an even older name that was first used in the s to describe what is now referred to as Vaseline glass. Some transparent yellow or yellow-green glass has been colored using additives other than uranium e. To confuse matters somewhat, this non-Vaseline glass might even be radioactive due to the presence of thorium impurities!

The two terms "vaseline" and "uranium" are often used to describe the same type of glass, but to be clear, while most vaseline glass has uranium content, there is a huge amount of uranium glass, of various shades of green and yellow, even blue, cream, and white, that does not fit the description of "vaseline".
