Vintage Green Uranium Mixing order Bowls ~ Set of 4

Product Name: Vintage Green Uranium Mixing order Bowls ~ Set of 4
Depression era set of 4 vintage green uranium mixing bowls circa 1930's. The bowls are unmarked. I believe they were manufactured by Federal Glass, possibly Hazel Atlas, sometime in the 1930's. Bowls do have some wear and minor scratches consistent age, but they look amazing. No chips or cracks detected. I bought these years ago and never used them. While not perfect, they do look to have been well cared for. The only flaws I noticed is that in the second to smallest bowl, there is a flaw inside the glass that I could not feel. See pictures 10 and 11. It's smooth to the touch. Smallest bowl has some minor scuffs from use in a few places. See last photo. Largest bowl is approx. 9 1/2" in diameter. 2nd largest is approx. 8 3/8" in diameter. 3rd is approx. 7 1/2" in diameter. Smallest is order approx. 6 3/4" in diameter. All glow under a black light. Please review photos. I encourage you to ask any questions you may have. I'm happy to try and answer. Ships from a smoke free home.
