Pyrex Glassware: Still Made in America

Past and Present

Since 1915, experienced cooks and beginners alike have reached for Pyrex® glassware products. It all started with our glass bakeware – loved for generations because it's affordable, durable, odor and stain proof, and great for cooking, serving and storing. Since then, new favorites have joined old standbys. The Pyrex line now includes products for the entire kitchen, including pots and pans, metal bakeware, and kitchen tools and gadgets. They're all designed and proven to make cooking a little easier. Today, approximately 80% of U.S. homes have Pyrex glass products, with many cooks passing them down from generation to generation – which we think is pretty neat.


The idea for Pyrex Glassware came from the industrious wife of a Corning Glass Works scientist who was frustrated with her unreliable casserole dish. Knowing the strength of the railroad signal lantern glass her husband worked with, she begged him to bring home something she could use in the kitchen. Voilà, the Pyrex baking dish was born. Two years later, Boston department store Jordan Marsh placed the first order for Pyrex Glassware. The rest, as they say, is history.
