About the Pyrex Brand

History of the Pyrex brand

    • The Pyrex® brand began with equal parts American invention and creativity. Initially created by Corning Glass scientists charged with developing lantern glass for railroads, the Pyrex brand found its way into the kitchen when Bessie Littleton, wife of a Corning scientist, asked her husband to bring home some heat-resistant glass to use in place of her broken casserole dish. He gave her the sawed-off bottoms of some battery jars and Mrs. Littleton used the glass jars to make a cake. She marveled at how evenly it baked, how she could actually see it baking in the oven and how easy it was to clean. This innovation spurred the first Corning casserole dish and after two years of research and testing, the Pyrex brand was officially launched in 1915.
    • The Pyrex brand has called the small town of Charleroi, PA, home for more than half a century. The manufacturing plant has employed generations of families throughout the Pyrex brand's proud history.
    • The Pyrex brand team is excited to usher in the next century of innovation, while remaining the trusted glass prep, bake and store solution for families across the world.

Pyrex Brand Facts

    • More than 80 million Americans own Pyrex products.
    • The first line of Pyrex glass bakeware in 1915 featured 12 pieces, including casserole dishes, custard cups, a bread/loaf pan, pie plates, egg dishes and individual bakers. Several Pyrex products offered today can trace their lineage back to these original 12.
    • While its signature clear glass revolutionized the way Americans baked at home, early Pyrex products also had a golden tinge that came from a chemical that helped to form the glass.
    • The first Pyrex measuring cup debuted in 1925 and had two spouts for pouring left handed or right handed. With the addition of red marking in 1941, the Pyrex measuring cup evolved to closely resemble the cups that are found in millions of homes across the world today.
    • Opal Pyrex kitchenware was introduced in 1947, with brightly colored pieces that included nesting bowls and casserole dishes with designs that were screen printed to the glass. While Opal Pyrex glassware production stopped in the 1980's, the pieces remain highly collectable and popular on social media today.
    • The most enduring and popular shapes today include the 3qt oblong baking dish, 9.5" pie plate, 2 cup measuring cup and 4 cup glass storage.
    • Pyrex glassware is has been made in Charleroi, PA for more than half a century.
