Manufacturing History

Made in the USA
PYREX® glass products sold in North America have been manufactured in the United States since 1915, and are currently manufactured at our Charleroi, Pennsylvania plant near Pittsburgh.

Glass Produced/Sold
Approximately 370 million PYREX® glass products have been manufactured by World Kitchen for sale in the marketplace since 1998. PYREX glass products are now in an estimated 80% of American homes.

Glass Material
PYREX® glass products are made using a tempered soda lime glass composite, as is the vast majority of consumer glass bakeware in the North American marketplace. The Cookware Manufacturers Association considers soda lime an appropriate material for glass bakeware.
