Corningware is a brand of oven-safe glassware that was first introduced in 1958. The dishware was originally made from a type of heat-resistant glass called Pyrex. However, in the 1970s, Corning began using a new type of material called Corelle. This material is made from multiple layers of fused glass, which makes it extremely durable and resistant to breaking. Corelle dishes are also safe to use in the microwave, making them convenient for busy families. Today, Corningware continues to be a popular choice for cookware and bakeware, and the company offers a wide variety of colors and patterns to suit any kitchen style.
