Along with Snowflake, the Pink Daisy pattern debuted Pyrex printed patterns on a solid color. Pink Daisy was also released on new sizes and shapes to the Pyrex line. First were oval Decorator Casseroles released in 1956 followed by square Space-Saver Casseroles released in 1957 and then oval Divided and Non-Divided (Open Baker) Dishes in 1958.
While Pyrex had been producing solid color dishes for several years Pink Daisy and Snowflake were the first patterned opalware to be released using a new screen-printing process. They were introduced as “NEW Pyrex Decorator Casseroles” and quickly became popular with consumers.
One of the selling points of this new casserole dish was its clear cover. The cover was marketed for multi-purpose use, meant to be used not only as a cover, but as a trivet to protect table surfaces or even as an extra serving dish.
When two sizes of the Space-Saver Casseroles hit the market in 1957 it was a new innovation with lids designed so they could stack on top of each other, thus saving space for other storage needs. Additionally, the Pyrex line offered this same combination of casseroles with aluminum covers for freezer storage. The Oven, Freezer, Server set (550) came with two casserole sizes, two aluminum Space-Saver covers and one “Sparkling Clear Cover” meant to be used for oven or freezer.
