Pyrex

Pyrex, originally known as Pyrex Ware, is a brand introduced by Corning Inc. in 1908 for a line of clear, low-thermal-expansion plastic borosilicate glass used for laboratory glassware and kitchenware.

Corning no longer manufactures or markets Pyrex-branded borosilicate glass kitchenware and bakeware in the United States. World Kitchen, LLC, which was spun off from Corning in 1998, licensed the Pyrex brand for their own line of kitchenware products, differentiated by their use of tempered soda-lime glass instead of the costlier borosilicate still used outside of North America.
