This is a set of three large vintage Federal Glass oven-safe mixing bowls. The bowls are made of milk glass and have a glossy finish. They are stackable and dishwasher, microwave, and oven safe. The set includes one 7" bowl and two 9" bowls, all in a round shape. The bowls are from the 1950s and are a solid white color with a vintage pattern. They are original and not a licensed reproduction. The production technique used is fused glass, and the backstamp is impressed.
