'''Pyrex''' ([[trademark]]ed as ''PYREX'' and ''pyrex'') is a [[brand]] introduced by [[Corning Inc.]] in 1915, initially for a line of clear, low-thermal-expansion [[borosilicate glass]] used for [[laboratory glassware]] and [[kitchenware]]. It was later expanded in the 1930s to include kitchenware products made of [[soda–lime glass]] and other materials.<ref>{{Cite web |date=November 24, 2014 |title=A CENTURY OF PYREX |url=https://www.cmog.org/article/pyrex |website=Corning Museum of Glass}}</ref> Its name has become famous for making rectangular glass roasters.

In 1998, the kitchenware division of Corning Inc. responsible for the development of Pyrex spun off from its parent company as Corning Consumer Products Company, subsequently renamed [[Corelle Brands]]. Corning Inc. no longer manufactures or markets consumer products, only industrial ones.
