One buyout firm quietly collected Pyrex, Corelle, Instant Pot, and Oneida. Farberware is a name on a 200-year lease. And the pans still wort
Pyrex was materials science before it was a brand. Corning invented it in 1915: borosilicate glass that shrugged off thermal shock. It is the reason three generations learned to take a dish from the freezer to the oven without a second thought.
One important aside about the product before the money story starts. The American Pyrex on shelves today is tempered soda-lime glass, a different material with a thermal safety margin an American Ceramic Society analysis described as borderline, roughly 55°C of headroom against 183°C for borosilicate. Consumer Reports collected 163 shattering incident reports, 42 of them involving injuries. European Pyrex, made by an unrelated company, is still borosilicate. The switch happened under Corning itself, decades before the buyouts. That is exactly what made the brand such a perfect acquisition: the glass had already been downgraded, the reputation had not.
An accounting of just how and why so many cookware names previously known for quality have gone downhill, and recommendations on which ones are still worth purchasing.
