The 1972 “Gifts” section of the Pyrex catalog displays the new Moon Deco 2 ½ quart casserole with lid (475). The advertisement shows an all-white opalware casserole with an opalware lid decorated with a large black circle with small white and red circles inside. This may have been the original iteration of Moon Deco because the most commonly found design has a red circle printed on both sides of the opalware casserole.
Moon Deco retailed for $5.95 and came with a black underplate.
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.
