Since 1958, Corningware has been a brand that’s helped plenty of home cooks around the world serve up a hearty meal. The super strong and easy-to-use materials that makeup Corningware products have made them a household name for many Americans. But can you put Corningware in the oven?
So, Can Corningware Go In The Oven?
As mentioned above, this product has incredible strength and durability, which means that pretty much all Corningware is safe to put in the oven.
In fact, according to the company itself, “all Corningware oven bakeware products can be used in conventional, convection and microwave ovens.”

Beware Of The Lids!
While all Corningware bakeware goods are safe to use in any type of oven, you should still be careful with any products that have a glass lid.
Corningware has only started selling glass lids with certain products in more recent years, and the manufacturer does state that the lids can be used in an oven but recommend doing so at a temperature lower than 350°F.
The main issue with these lids is that they can’t undergo sudden changes in temperature without the risk of them breaking or shattering.
Similarly, it’s not a good idea to place your Corningware bakeware products in a freezer with a glass lid on top. Instead, it’s recommended that you cover the top with foil or plastic wrap.
A Brief History Of Corningware
The Corningware brand has an interesting history and has contributed some pretty substantial technological developments in the cookware world.
It all started in 1953 with Donald Stookey, who worked in the research and development division of Corning.
Stookey was working with a special kind of glass that he wanted to heat in a furnace at a temperature of 600°F.
However, when he realized that his furnace was at 900°F and the glass had turned a white color, he tried to throw his sample away.
Stookey accidentally dropped the milky white glass sample and, to his surprise, it hit the floor without shattering.
This is how he discovered the material known as Pyroceram, which was then used to manufacture all kinds of bakeware goods for Corningware.
The company enjoyed great success for several decades until the start of the 21st century when production was halted in the US.
It wasn’t until 2008 when Corningware reintroduced its Pyroceram-based products to the US market and popularity re-surged.
Interestingly, Corningware’s biggest problem as a business has been how durable its products are. They found that sales were often restricted to new customers because the products rarely ever broke and needed replacing.
Talk about suffering from success!

What Makes Corningware So Great and Oven Friendly?
The reason Corningware products are so popular and successful is because of the Pyroceram material used to manufacture them.
Pyroceram has a fantastic resistance to thermal shock, being able to withstand temperatures of up to 840°F. That’s way hotter than anybody’s home oven could ever get!
This resistance also makes Corningware products great for sudden changes in temperature. For example, you can easily transfer a dish full of leftover food from your freezer, straight to a hot oven without risk of damaging it.
Similarly, the material is very strong and durable so poses little risk of breaking or shattering, even when dropped from a decent height.
The versatility isn’t just restricted to the oven, though. Corningware products are just as well suited to being used in a microwave or on a stovetop. Basically, the list of things you can do in a kitchen with a Corningware product is pretty much endless.
Many customers have reported using their Corningware products for several decades, with sets often spanning generations of the same family.

Corningware Product Range
A lot of Corningware’s older products are considered vintage these days. Their bakeware was once famously designed with a blue cornflower pattern that made them stand out from the competition.
In the modern day, this pattern no longer persists but the company still produces a great range of cookware tools that you can purchase online.
The Corningware 12-piece ceramic bakeware set is a great example of the range of different dishes the company produces.
It includes 6 different-sized dishes that can just as easily make a casserole for the whole family as they can make a small dessert like a tart.
Also included is a series of glass and plastic lids that offer multiple ways to cook and store your food.
As we mentioned earlier, it’s never a good idea to freeze leftover food in a Corningware dish with its glass lid on top. Instead, you can now use the plastic lids provided, which pose no threat of shattering and ruining your food.
This set also evidences the fact that Corningware no longer produces Pyroceram products nearly as much as it used to.
Some customers have said how they yearn for the good old days of super resilient Corningware products but the ceramic makeup of these dishes proves that the modern methods are just as good.
These dishes are incredibly durable and can easily last over a decade if you treat them right.

Theoretically, the highest temperature that old-fashioned Pyroceram Corningware dishes can withstand is around 840°F, which is a whole lot hotter than any conventional home oven.
However, the more modern products from Corningware are often made from ceramic, which has an even greater thermal resistance and can withstand around 1000°F!
