With the increased use of microwave ovens in the 1970s it was no longer practical for Pyrex to be made with gold patterns. However, Corning Glass Works was still releasing patterns created as a response to trends in the consumer market. The 1978 release of Daisy is just such an example. Unofficially known as Daisy Silhouette, Daisy had a light yellow background with a pattern of large orange outlined daisies indicative of the “Flower Power” movement started in the late-1960s.

Daisy Silhouette was a part of the “Designer Collection,” released simultaneously in 1978 with Terra Cotta Rose, Dynasty, Spices and Wheat. Daisy Silhouette was released on the one-quart Round Casserole (473) and came with a Rattan Trivet.

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 candle warmers 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 intended to be reflective of the specific pattern.
