"Pyrex (trademarked as PYREX) is a brand introduced by Corning Inc. in 1908 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. Pyrex sold in the United States is made of tempered soda-lime glass; outside of North America the costlier borosilicate is still used.

Corning no longer manufactures or markets Pyrex-branded borosilicate glass kitchenware and bakeware in the US. World Kitchen, LLC, which was spun off from Corning in 1998, licensed the pyrex (all lower case) brand for their own line of kitchenware products—differentiated by their use of clear tempered soda-lime glass instead of borosilicate."
