For less than $140, a solitary casserole dish from the 1960s version of the brand can sell for multiple thousand dollars. How then would one determine whether your CorningWare holds value?
CorningWare’s composition has undergone several changes over time; however, the Pyroceram versions are highly prized nowadays and were manufactured between 1958 and the late ’80s. The Pyroceram product line boasts an impressive resistance to extreme heat, allowing items to be moved directly from the freezer to the oven without issue. This feature also ensures they’re suitable for stove-top cooking, indicated by a little flame symbol. Authentic vintage CorningWare often features a scripted company logo that remained unchanged until 1998, along with the label “Made in the USA.” Additionally, verify whether your piece bears a smooth edge as opposed to a flanged one—this latter trait denotes a more recent production method.

Why Is Vintage CorningWare Unique?
Classic CorningWare distinguishes itself through its utility and design.
A kitchen mishap involving an oven resulted in the creation of CorningWare.
In the early 1950s, Stanley Donald Stookey conducted experiments involving photosensitive glass inside an oven. During one of these trials, he inadvertently raised the temperature to 900 degrees Fahrenheit expecting to see melted glass due to overheating; however, what emerged from this accident was not shattered remains but rather a piece of glass displaying a cloudy white hue — which surprisingly did not shatter upon being dropped. This innovative substance came to be called Pyroceram and later established itself as part of CorningWare when the product range launched in 1958. It stood out for being able to transition seamlessly between freezers, ovens, microwaves, and stove tops—a rarity among kitchen utensils at the time. Early versions of CorningWare featured pristine whites adorned with blue cornflower designs, remaining highly sought after patterns until now. Apart from those classic floral motifs, retro enthusiasts also cherish checkered red-and-white combinations alongside winter-themed snowflake prints. Furthermore, timeless colors such as avocados greens and golden-hued harvest tones continue to evoke nostalgia amongst collectors and home cooks alike.
In the year 2000, CorningWare ceased production of their cookware utilizing Pyroceram and transitioned to glazed stonewear, which isn’t suitable for use on stove tops. However, this robust material made a comeback in 2008 when Corelle acquired the brand and outsourced manufacturing to Keraglass in France—a company capable of producing Pyroceram. Currently, today’s CorningWare includes these advancements.
