Uranium glass, also called Vaseline glass due to its oily-yellow hue, is a type of glass that has uranium oxide added to the mix before melting. This glass was first created in the early 19th century, with documented production as far back as the 1830s in Bohemia (modern-day Czech Republic). During the Victorian era, it became highly popular for its vibrant color and ability to fluoresce under UV light. Production peaked between the 1880s and 1940s, especially in Europe and the United States. Uranium was added in small, safe amounts (usually 0.1%–2%) to create yellow, green, and sometimes even blue glowing glassware. 🛠️ Ideal for crystal collectors, DIY resin artists, mosaic makers, witchy decor lovers, and anyone fascinated by radioactive vintage materials.
