The Stack ‘N’ Snack Set was released in 1980 and is unofficially known as Speckled Lines. The 1980s version of a Chip N’ Dip, this set included the four-quart mixing bowl (404) and the ten-ounce Bowl (708), as well as a wooden serving coaster that attached to the large bowl on which the ten-ounce bowl perched. The 708 bowl is not a standard size, but was borrowed from the PYREX restaurant line. This set is part of the Hospitality Collection along with the two new Bake N’ Carry casseroles.
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.
