READY TO SHIP CULLET - A piece of uranium glass, Czech Republic (26 Aug 2026)

Other sizes are available on request. Number on the cullet is weight in grams. The most common color of uranium glass is pale yellowish-green, which in the 1930s led to the nickname "Vaseline glass", based on a perceived resemblance to the appearance of Vaseline-brand petroleum jelly as formulated at that time. Specialized collectors still define Vaseline glass as transparent or semi-transparent uranium glass in this specific color. The glass has green fluorescence under UV light. [Wikipedia]
