Three USA made blue glass nested mixing bowls from Anchor Hocking, both oven and microwave safe. The largest bowl holds 2-1/2 quarts, measuring 8-1/2" diameter by 4-1/4" deep. Next is the 1-1/2 quart, 7-1/2 by 3-3/4 inches deep. The small bowl has a 1 quart capacity and is 6-1/2 by 3 inches.

The coloring is transparent dark blue, but not as dark as cobalt. The bowls have some stirring and storage marks, the larger bowl having more wear than the others. This one also has a smooth to the touch narrow flake along the interior rim, more easily felt than seen.
