High quality product as it is produced by the well-known Pyrex company. Bessie Littleton, wife of physicist Jessie Littleton, an engineer at Corning, originated the brand. Her long experience with broken or cracked dishes after just one cooking in the oven pushes her to ask her husband for the bottoms of Nonex laboratory containers, to test the cooking of a Savoy Cake. A real success! Bessie tries again with all kinds of recipes and ingredients, potatoes, meat... His successes convince the management of Corning, which decides to start producing kitchen utensils. All that's missing is a name to introduce itself to the public. Pyright is thought of first, as it was initially used as a pie plate. The name quickly morphs into Pyrex, rhyming with Nonex. Very soon, advertising became enthusiasti.
