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.
In 1941, we introduced measuring cups that can be more easily measured with a red grid, cooked more conveniently, pink mixing balls made in pink in the 1950s fashion, and a yellow storage container with a 1960s pattern.
In2012, we developed a sealed container with a plastic lid with ventilation holes and an internal hermetic system capable of using a microwave oven. Led innovation.
Shortened cooking time
Easy to check cooking process
Preventing pressure on the bowl
More uniform baking is possible
Material that does not harm food
In 1908, heat-resistant glass developed for railroad lanterns was rebuilt for kitchen in 1913. The scientist's wife, Corning Glass Works, who developed a railroad lantern that could withstand rapid temperature changes, wondered if there were any products that would not break easily if it had just been used twice in the past. The next day her husband made a sponge cake with a small bottle of heat-resistant glass material brought from the company and had an amazing experience.
