Corningware is a type of oven ware, made by the Corning Glass Works in upstate New York. It first came on the market in 1868 and was originally sold as Pyroceram, but later changed its name to Corningware after it gained popularity.

How can you tell if corningware is Pyroceram? |

It’s likely stoneware Corning Ware, not Pyroceram, if you purchase brand-new Corning Ware at the shop and it doesn’t appear too pricey.
