Uranium glass is a type of glass that contains uranium, usually in oxide form, to give it a yellow-green color and make it glow under ultraviolet light. It is a fascinating collectible that has been around for centuries, but also has a dark history linked to the atomic age.
Uranium glass was first identified in 1789 by a German chemist named Martin Heinrich Klaproth, who also discovered the element uranium. He named it after the planet Uranus, which had been discovered eight years earlier. Uranium glass was popular in the 19th and early 20th centuries for its decorative effect and was used to make various items such as tableware, jewelry, lamps, and figurines.
Uranium glass comes in various shades and forms, such as Vaseline glass, custard glass, jadite glass, and depression glass. Each type has its own characteristics and value for collectors. For example, Vaseline glass is a transparent yellow-green glass that resembles petroleum jelly, while custard glass is a opaque pale yellow glass that resembles custard. Jadite glass is a opaque jade-green glass that was popular in the 1930s and 1940s, while depression glass is a cheap mass-produced glass that was made during the Great Depression.
The most distinctive feature of uranium glass is its ability to fluoresce bright green when exposed to ultraviolet light, such as a blacklight. This is because the uranium atoms in the glass emit electrons when they absorb UV photons, creating a visible glow. This effect can be used to test the authenticity of uranium glass, as well as to enhance its beauty.
However, uranium glass also has a darker side. Uranium is a radioactive element that can cause health problems if ingested or inhaled. Uranium glass is not very radioactive and poses little risk to humans, but it still raises some concerns about its safety and environmental impact. Uranium glass declined in use after World War II due to the scarcity of uranium and the public fear of radiation. Uranium was diverted for military purposes, such as making atomic bombs and nuclear reactors.
Today, uranium glass is mostly collected by enthusiasts and hobbyists, who appreciate its history and aesthetics. Uranium glass can be found in antique shops, flea markets, online auctions, and museums. Some modern artists also use uranium glass to create new works of art that explore its properties and meanings.
