Pyrex tempered glass bakeware, mixing bowls, and food storage are manufactured in Charleroi, Pennsylvania, where the company has pressed American glass for decades. The tempered soda-lime formula stands up to oven, microwave, freezer, and dishwasher transitions, and the clear glass body lets cooks see browning, layers, and doneness without cracking a lid. Pyrex has been a kitchen fixture in American homes since 1915.
A two-pack of Pyrex Basics 9-by-13-inch oblong baking dishes — the standard American casserole, lasagna, and sheet-cake size. The 3-quart volume holds a full baked pasta, a pan of brownies, or a sheet of roasted vegetables with room to spare. Two-pack means one goes into the oven while another is prepped and ready on the counter.
Pyrex was introduced in 1915 by Corning Glass Works as a borosilicate oven-safe glass, and the brand transitioned to tempered soda-lime glass in the 1990s — the current formula produced at the Charleroi, Pennsylvania plant. The brand is now operated by Instant Brands and remains the most recognized name in American glass bakeware and food storage. Charleroi employs American glassworkers, mold operators, and finishers across every shift.
