This is a set of 6 beautiful green vintage uranium depression juice glasses with crinkle and ribbed design. A lovely mid century modern set! There is a faint green glow under the black light. It may be depleted uranium glass which were a type of glass made after WWII. Those made before the war used natural uranium. The uranium content of some glass manufactured in the early 1900s, reached as high as 25%. Measures about 3.5” high x 3.5” wide. There are no cracks or chips. It’s a thicker quality of glass. No makers mark. Brand is unknown. Please review ALL pictures before purchase.
