Pattern Description: Unofficially known as “Eyes” this set is one of the first patterns released as a Chip and Dip set. Using a metal bracket the set combined the 401 dip bowl and the 403 mixing bowl to create the Hot ‘N’ Cold Chip and Dip Set. The characteristic Pyrex stamp on the bottom of each dish does not appear on some of the Eyes bowls while others are clearly marked with the stamp. A corresponding coffee carafe printed with the “Eyes” pattern in gold was released as well as a clear one-quart juicer with a turquoise plastic lid. Corning Glass Works offered its first patterned opalware gift set in 1953 when the Heinz Baking Dish was sold in grocery stores. Widespread distribution of promotional patterns occurred after the overwhelming success of the 1956 release of seasonal “decorator casseroles.” Using existing Pyrex shapes, gift sets featured new patterns offered for a limited production time. They often came with mounters, cradles, or candlewarmers and were advertised in the spring to appeal to Mother’s Day and summer wedding shoppers and in the fall to give the holiday gift-buyers something new. Corning continued to produce gift sets through 1983, creating nearly 135 different gift set patterns during that time. Corning intended these pieces to be sold for a limited time, and directed retailers to remove older, unsold promotions from the shelves. Often, patterns used for these gift items were unnamed, or given names descriptive of the dish’s purpose, like “chip and dip set.” Collectors over the years have assigned names more reflective of the specific pattern.
