These beautiful green depression glass cereal bowls make stunning serving dishes for berries, candies, or dips. Green Block Optic was made by Hocking Glass from 1929 to 1933. The pattern, Block Optic, is named for its block design. There are horizontal rings molded into the glass forming three rows of blocks. Each green Depression Glass bowl measures 5-3/8 inches in diameter and about 1-1/4 inches deep. There is no mark. Two bowls are offered here, each is in good condition. There are expected minor surface scratches but no damage. The smudge in the bottom of the bowl is sticker residue that will be removed. I'm so happy you stopped in to Maggie Belle's Memories!
