Corning "Pyrex Snowflake Blue" Covered Refrigerator Dish, 1972-1975

Corning Glass Works' heat-resistant glass bakeware, Pyrex, was introduced in the mid-1910s. Pyrex products were inexpensive, with an easy-to-clean smooth surface. The glassware could travel from refrigerator to oven to table. Corning introduced colored Pyrex kitchenware in 1947, and later, produced dishes in an array of patterns, like this Snowflake Blue refrigerator dish made from the early 1970s.
