The Pyrex® brand story starts with equal parts of American invention and creativity. The heat-tempered glass that is the foundation of the Pyrex brand was created years earlier by Corning Glass scientists charged with developing lantern glass for railroads. They needed to tackle a particular problem-the heat of the lantern flame conspired with the cold air of winter to shatter traditional glass. They needed a glass that could handle changes in temperature.
By 1913, the glass was used in a number of industrial applications. But it found its way into the kitchen when Bessie Littleton, wife of a Corning scientist, asked her husband to bring home some glass to use in place of a broken casserole dish. He gave her the sawed-off bottoms of some battery jars.
A cake was baked, an iconic brand was born and, as they say, the rest was history.
Like the properties of the glass, the core benefits of Pyrex brand cookware remain the same to this day.
