What is Corningware and How Has It Evolved?
Corningware, a name synonymous with durable and versatile cookware, has a rich history dating back to the 1950s. Initially, Corningware was crafted from Pyroceram, a revolutionary glass-ceramic material developed by Corning Inc. This innovative material could withstand extreme temperature fluctuations, making it ideal for oven-to-table use and even stovetop cooking. The original Pyroceram Corningware was known for its signature white color and often featured decorative patterns like the iconic Blue Cornflower. However, the composition of Corningware underwent a significant change in the late 1990s when the brand was sold. The new owners switched from Pyroceram to a more conventional ceramic stoneware, which, while still durable, lacked the thermal shock resistance of its predecessor. This means that while vintage Pyroceram Corningware can handle the heat of a stovetop, newer stoneware versions are not designed for such use and could crack or break under direct heat.
How do I identify if my Corningware is stovetop safe?
Identifying whether your Corningware is safe for stovetop use involves examining its markings and material. Older, stovetop-safe Corningware made of Pyroceram often has an embossed stamp on the base, sometimes including the word “Pyroceram” or a stylized flame logo. These pieces may also have a smooth, glazed bottom. According to a discussion on GardenWeb, if the bottom is flat and finished like the rest, it is safe for range top use. If it is like stoneware with an unglazed feel, it is not. Newer stoneware Corningware, not suitable for stovetops, usually has an unglazed, rougher bottom and may carry a warning against stovetop use. If unsure, consult the manufacturer or err on the side of caution by avoiding stovetop use.
What are the risks of using non-stovetop safe Corningware on a glass top stove?
Using non-stovetop safe Corningware on a glass top stove poses several risks. Firstly, the Corningware itself could crack or shatter due to thermal shock, especially if it’s made of stoneware. As mentioned on Hunker, the newer ceramic formula is more fragile and not recommended for stovetop use. This not only ruins the dish but also creates a potential safety hazard with sharp fragments and hot food spills. Secondly, the rough bottom of stoneware Corningware can scratch and damage the smooth surface of the glass top stove, leading to costly repairs or a compromised cooking surface.
