About Pyrex

Today's kitchenware designed for 100 years

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.


That homespun ingenuity has infused the Pyrex brand in the decades since. A distinctly American brand—Pyrex glassware has been used by generations of cooks and bakers from coast to coast. Pyrex brand’s designers develop practical refinements and unexpected uses for their products. Far more than a simple bakeware, it inspired new kinds of recipes, budgeting advice and decorating tips—all of which the Pyrex brand has published and shared with its customers. Over the years, the brand has en-couraged efficiency by helping cooks to simplify the process with reliable results. And looking forward, Pyrex brand’s team aims to continue developing material and use innovations to ensure that our products remain a mainstay in American kitchens and addition to rest of the World for generations to come.

Leading innovation and trends in kitchen design for 100 years

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.

The Amazing Facts of Pyrex Glass Through Baking


Pyrex! A symbol of solidity and firmness
It’s the first heat-resistant glass, positioned in the kitchen

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.
