Along with the White Lace Decorator Casserole, the Black Needlepoint Square Space-Saver and the Black Tulip Casserole, the Pressed Flowers Cradled Decorator Casserole was the first promotional item to have a printed design on its side. Previous promotional dishes were either white or solid in color with no design.

Released in 1957 on the 1 ½ quart (043) and 2 ½ quart (045) Oval Casserole, this dish was officially known as the Cradled Decorator Casserole. Known unofficially as Pressed Flowers, this casserole is yellow with designs of various types of charcoal-colored flowers along the sides.

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.
