These Block Optic Green Depression Glass Sherbets were made by Hocking Glass between 1929 and 1933. Named for its block design, this pattern has horizontal rings and a vertical optic molded into the glass forming concentric rows of blocks.
Each sherbet measures 3-inches tall and 3-1/2 inches in diameter. The rayed foot is just under 2-1/2 inches in diameter. There is no mark.
As in most vintage pieces, there are normal, small surface scratches, and one sherbet has a bit of roughness on the underside of the foot. The other has a 1/2-inch long, curious group of curved scratches on the outside of the glass. These are grouped together and resemble a tangled bunch of four or five hairs. They do not go through the glass, but are easily felt on the outside.
The Block Optic pattern was made in several variations. These are the slightly shorter, heavier sherbets. There is a slightly taller, thinner Block Optic sherbet also available in my shop.
