Corning Glass scientists tasked with developing a lantern glass for railroads that could handle changes in temperature built the foundation for the Pyrex? brand; by 1913 the versatile glass was used in a variety of industrial applications but only when the wife of a Corning scientist ask her husband to bring home some glass to use in place of a broken casserole dish was the concept of Pyrex? bakeware born. Today the venerable tempered glassware is used as the basis for kitchenware including bakeware, ovenware, serveware, cooking prep and food storage solutions. The product line includes measuring cups, mixing bowls, glass food storage bowls, pie dishes, bakeware sets, casserole dishes, baking dishes, loaf pans, food storage containers and more. The glassware is BPA-free and safe to use in the oven, microwave, dishwasher and freezer; it is proudly made in America and has been a favorite of cooks and bakers for generations.
