Who invented pyrex

After experimenting with all sorts of recipes side dishes like potatoes or even meat dishes her success finally convinced Corning to launch themselves in creating kitchen utensils.

Canulas, syringes, suction cups, spittons, dropper, etc… A wide range of Pyrex glass hygienic products, resistant to boiling water, flames alcohol and other chemical agents is developed. It is not only reliable, but also a very safe and hygienic product, it has everything to persuade and reassure young mothers. The factory at Bagneaux-sur-Loing was quickly overflowed with too many orders. It is the implementation of a semi-automatic machine Until now, the baby bottles were blown manually that helped increase efficiency in the factory.

The arrival of electricity has revolutionized the way people cook. Ovens that run on gas-electricity or on coal-electricity were in full bloom. The production of glass products was gradually reduced in Bagneaux-sur-Loing and the factory in Chateauroux quickly became the main production site. In , Eugene Sullivan, Director of Research at Corning Glass Works, developed Nonex, a borosilicate low-expansion glass, to reduce breakage in shock-resistant lantern globes and battery jars.

Sullivan had learned about Schott's borosilicate glass as a doctoral student in Leipzig, Germany. Jesse Littleton of Corning discovered the cooking potential of borosilicate glass by giving his wife a casserole dish made from a cut-down Nonex battery jar. Corning removed the lead from Nonex, and developed it as a consumer product.

Pyrex was also literally cleaner: Smells didn't cling to or seep into the glass the way they did with ceramic, earthenware, cast iron and tin, and the glass didn't rust.

Efficiency was also part of the home economics movement, and Pyrex dishes, marketed as being able to cook food quicker, meant that women could save time and fuel.

Pyrex's efficient cooking, its material and domestic manufacturing made it indispensable during World War II, when families were instructed to conserve energy, metal was scarce and glass imports from Germany were cut off. During World War II, ads emphasized that using Pyrex was patriotic; one read, "My wife sure makes food fight for freedom!

Over the following decades, Corning would apply color and decorative patterns to opalware, creating more than distinct designs. With new, spacious kitchen designs, dishes were on view for all to see. With colored Pyrex came the oven-to-table idea, which had always existed but was adopted by wealthier households after the war. Most people associate Pyrex with brightly colored pieces from the '50s; turquoise pieces—such as ones with the "Butterprint" pattern, depicting an Amish farming couple—and pink pieces, are especially popular with collectors.

In the '60s, the tones became earthy and muted, as in the "Terra" pattern, characterized by a black exterior and simple, thin rings of brown.

The Corning Museum of Glass exhibit includes advertisements, ephemera and a wide variety of products from the brand's history: everything from an elegant cut-glass teapot from the '30s to casserole dishes in psychedelic hues from the '70s.

In a large atrium, a long wall is filled with row after row of opalware patterns—nearly in total—in a crazy rainbow of colors. For instance, there's a '70s avocado green that I recognize from my parents' kitchen," Brumagen says. Colors and styles may have changed, but temperature-resistant glass stood the test of time. In the '70s and '80s, Pyrex only became more relevant as microwaves were adopted. Originally, there was an incredible variety of sizes and styles of Pyrex dishes, Brumagen says; there were more than styles according to a ad.

Now, some of the same products are produced, but with less variation. Transparent ovenware, especially, has not changed much over the years. But Pyrex's history is not without controversy. Around the '50s, Corning began making Pyrex out of thermally tempered soda-lime glass, which is less expensive to produce, instead of borosilicate glass. Other companies are still using borosilicate; in fact, Pyrex that's produced in Europe is still made using borosilicate glass. In recent years, Consumer Reports has documented hundreds of cases of Pyrex dishes shattering and injuring users, but the magazine's tests have been inconclusive.
