Uranium glass, also known as vaseline glass, is a unique type of glassware that contains uranium oxide, giving it a distinct yellow or green hue and a fascinating glow under ultraviolet light. This glass, popular from the late 19th to the early 20th century, is prized by collectors for its aesthetic and historical value.
What Makes Uranium Glass Unique?
Uranium glass is distinct due to its fluorescent properties. When exposed to UV light, it emits a bright green glow, a result of the uranium content. This characteristic makes it a favorite among collectors and enthusiasts. The glass was often used in decorative items, such as vases, bowls, and jewelry, and its production peaked in the early 1900s.
How is Uranium Glass Made?
The production of uranium glass involves adding a small amount of uranium oxide to the glass mixture. Typically, the uranium content is low, usually between 0.1% and 2% by weight, which is enough to produce its signature glow without significant radiation risk. The process requires careful handling to ensure safety and achieve the desired visual effects.
Is Uranium Glass Safe?
While uranium is a radioactive element, uranium glass is generally considered safe to handle. The radiation levels are typically low, posing minimal risk to users. However, it is advisable to avoid using uranium glass for food storage or consumption to prevent any potential leaching of uranium into food or drink.
The History and Popularity of Uranium Glass
Uranium glass became popular in the 19th century, with its peak during the Art Deco period. Its unique appearance made it a favorite for decorative pieces. The production declined after World War II due to the increased regulation of uranium and the advent of new glass-making technologies.
