Pyrex was founded in 1908 in Corning, NY. Corning Glass Works started making Nonex, a thermally resistant “non-expansion glass,” for railroad signal lanterns and other industrial applications. It was clear glass at first and once it was discovered that it was useful in the kitchen, (because of its durability and resistance to high temperatures, it didn't change the taste of food, and didn't retain smells), it was marketed for domestic use. By 1915, Corning was selling Pyrex pie plates, casserole dishes, and bakeware, originally made from Borosilicate glass, to the housewives of America. The opaque pieces didn't start until 1936 when Corning bought a glass factory in Charleroi, PA, which could produce colorful opal glass and had the same properties as the clear glass being made in NY. Corning released the iconic primary-colored Pyrex nesting bowls in 1945. 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”. Corning Glass Works produced more than 150 different patterns of bowls, casseroles, refrigerator dishes, and more in a host of shapes and sizes. After 1998, by nearly all accounts of Pyrex history shows, they switched from borosilicate glass to the cheaper, but even more thermal resistant, Tempered Glass (soda-lime glass). Corning no longer manufactures or markets consumer glass kitchenware and bakeware. Corelle Brands, which was spun off from Corning Inc. in 1998, originally under the name Corning Consumer Products Company, continues to license the "pyrex" (all lowercase) brand for their tempered soda-lime glass line of kitchenware products in the United States, South America, and Asia. In Europe, Africa, and the Middle East the "PYREX" (all uppercase) brand is licensed by International Cookware for use on their borosilicate glass products. It is a well known fact that most people will keep their Pyrex for a lifetime and even pass it down to the next generation.
