These three Mid Century white glass nested mixing bowls are Fire King from Anchor Hocking. There were a number of Fire King mixing bowl styles and shapes - this one with the wide flat bands below the rims was called Colonial Kitchen. Bowl sizes are 8-3/4" diameter by 4-1/4 inches deep, 7-1/2 by 3-1/2, and 6 by 3 inches. All three bowls are in excellent condition, still glossy with no damage or stains and very minimal stir marks in the bottoms.
