uranium glassware

Uranium glass, also known as Vaseline glass due to its greenish-yellow tint, is a unique type of glass that has a small amount of uranium oxide added to the glass mix. Here are some interesting facts about it:
1. Unique Glow: One of the most striking features of uranium glass is its fluorescent glow under ultraviolet (UV) light, or blacklight. This glow is due to the uranium content in the glass, which fluoresces bright green under UV light.
2. Radioactivity: Uranium glass contains trace amounts of uranium (typically between 0.1% and 2% uranium oxide). While this does make the glass slightly radioactive, it’s generally considered safe to handle because the levels are low. However, collectors are cautious about prolonged or close exposure.
3. Historical Popularity: Uranium glass became popular in the 19th century, especially during the Victorian era, and was widely used until World War II. Production declined when uranium was prioritized for nuclear weapons and power.
4. Color Range: Although uranium glass is often green or yellow, it can also come in colors like blue, pink, and even clear. The exact color depends on the other elements mixed with the uranium oxide in the glass.
5. Collector’s Item: Today, uranium glass is highly collectible, with pieces often found in antique shops and online auctions. The uniqueness of the glow and its historical value make it attractive to collectors.
6. Not Just Glassware: Though commonly found in dishware, vases, and decorative objects, uranium was also used in glazes for pottery and ceramics to produce vibrant colors
