Pyrex

Pyrex

Pyrex (trademarked as PYREX) is a brand introduced by Corning Inc. in 1915 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. It was later expanded to include clear and opal ware products made of soda-lime glass. Corning no longer manufactures or markets consumer glass kitchenware and bakeware. Corelle Brands, which was spun off from Corning Inc. in 1998 under the name Corning Consumer Products Company and since renamed, continues to license the pyrex (all lowercase) brand for their tempered soda-lime glass line of kitchenware products sold for the consumer market in the United States, South America, and Asia. In the regions of Europe, Africa, and the Middle East, the PYREX (all uppercase) brand is licensed by International Cookware for use on their borosilicate glass products. The brand name has also been used for non-glass kitchen utensils and cookware in various regions for several decades.
