Vintage Green Uranium Glass Ribbed Sherbet Cup

Uranium glass, often referred to as Vaseline glass due to its characteristic yellow-green hue and tendency to glow under ultraviolet light, contains a small amount of uranium oxide. This addition not only gives the glass its unique color but also causes it to fluoresce brightly. While the uranium content is minimal and considered safe, its presence makes these pieces highly collectible and sought after by enthusiasts.
