Can Corningware Cookware Go in the Oven?

Yes, you can use CorningWare inside the oven up to the maximum temperature limit written on the instruction booklet of the manufacturer.

Corningware cookware made from glass-ceramic can withstand high temperatures while those made from stoneware and porcelain can withstand heat only up to a certain temperature.

In simple words, if you need it inside the oven for cooking a particular recipe, check for the temperature you need and the maximum temperature your CorningWare can withstand. 

A word of caution: vintage CorningWare made before the year 2000 is not oven safe and may break.

Allow me to divulge all useful details regarding your CorningWare cookware. 

What is CorningWare?

CorningWare cookware is excellent quality cookware manufactured by Corelle brands and made in Illinois, United States.

Let us move on to some frequently asked questions : 

What is the Maximum Temperature Limit for CorningWare Cookware? 

You must always read the manufacturing booklet that came with your cookware and follow the temperature guidelines. 

According to their website,  CorningWare can be safely used up to 350-450 degrees Fahrenheit. The stoneware and porcelain models usually have a temperature limit of 350 degrees Fahrenheit. High-quality CorningWare like those made from glass-ceramic can safely withstand 450-500 degrees Fahrenheit.

Are all Corningware Products safe for use in Oven? 

Yes, all cookwares under CorningWare are safe for oven use due to their ability to withstand high temperatures.

They are also protected from thermal shock and can be used immediately in hot and cold environments alternatively. 

Glass-ceramic ware is the best of the lot for oven use although the CorningWare collection of glazed stoneware and ovenware also gives a  great performance inside the oven up to 350 degrees Fahrenheit. 

Stoneware is not very resistant to thermal shocks so you need to bring a frozen dish down to room temperature before placing it in an oven. 

You must always check the manufacturer’s recommendations for your particular product regarding the temperature limitations.

Each product may be different and have different temperature resisting capabilities. It always pays to be safe than sorry. 

Can I use Vintage CorningWare Inside the oven? 

Please don’t use vintage CorningWare for oven use. The composition of the old CorningWare is way more different compared to the new CorningWare.

Due to the different make, the ability to withstand high heat becomes different.

While the new model can withstand a good amount of heat up to 500F, the vintage models may break down at high temperatures inside the oven. 

The vintage products are durable and long-lasting but their maximum temperature ability inside the oven is questionable. 

Always read the product labels and follow the manufacturing instructions regarding your CorningWare cookware. 

Are all Corningware Cookware Safe Under the Broiler?

You can use most of the CorningWare cookware under the broiler. However, the maximum temperature limit is different for different CorningWare cookware so check for individual heat/temperature tolerance.

Let me explain. Broiling occurs in a  temperature range between 500-550 degrees. Some of the CorningWare products are safe only up to 400-450 degrees Fahrenheit. 

This makes them unsafe for broiler use. The cookware can crack and break under intense heat. 

All CorningWare products under Glass ceramic and some products under Pyroceram are broiler safe. Porcelain and stoneware products are not broiler safe.

The company specifically mentions which cookware is oven safe and which ones are broiler safe. Do not confuse the two markings. 

Play safe and use those CorningWare products that can withstand high temperatures of 500F and above.

You can easily find the maximum temperature limit in the manufacturing booklet.  

Are the Glass Lids of CorningWare Cookware Safe for Oven Use? 

According to the manufacturers, not all Corningware glass lids are oven-safe. Also, the glass lids cannot withstand thermal fluctuations. 

They recommend preheating the oven before using the glass lid and to use glass lids only up to 350-400 degrees.

Preheating the oven will protect your glass lid from thermal shock and prevent undercooking. 

Most of the new versions of CorningWare glass lids are made from soda-lime or tempered borosilicate.

Both the materials have low-temperature tolerance and low thermal shock ability. 

Always read the product labels and the maximum heat tolerance in the instructions before placing the glass lid with CorningWare cookware inside the oven.  

Using a glass lid beyond its maximum temperature ability will cause it to shatter and break inside the oven harming the food contents as well the interiors of the oven. 

If you are placing your bakeware directly from the oven into the fridge, remove the glass lid. Allow it to reach room temperature before placing it inside the fridge. 

In the same way, allow the glass lid to reach room temperature before placing it inside a preheated oven. 

Do not use a glass lid in the freezer. Cover the top of your bakeware with foil instead.  

Let us move on to tips for better care of your CorningWare cookware 

Tips for Using CorningWare Cookware 

CorningWare cookware is extremely durable and versatile.

By following the tips below you can use your CorningWare cookware for many years: 

  • CorningWare retains heat well. You can switch off the oven and rest assured your food will remain warm for a long time while saving your electricity bill
  • As the CorningWare will remain heated up after cooking, Use oven mitts or pot holders while removing the cookware from the oven.
  • Use wooden ladles or plastic spoons to stir up your food. Metal spoons can scratch and damage CorningWare cookware. 
  • For a long life span, clean with non-abrasive cleaners and warm soapy water. 
  • Let the glass lids reach room temperature before exposing them to preheated oven or warm water for cleaning
  • Being ceramic and glass, CorningWare is susceptible to breakage. Handle with care and make sure it does not come in your way or slip out of your hands. 
  • Do not use the bakeware for caramelizing sugar, making popcorn, or deep frying 
  • Put a little water inside the CorningWare dish when using it for frozen food. 
  • To prevent undercooking and overcooking, always preheat your oven before placing your cookware
  • Do not place an empty Corningware dish inside a high-temperature oven 
  • Cracked/chipped or broken cookware should not be used for the oven as that can worsen the body, adulterate the food and spoil the cookware further.
  • Before placing the CorningWare cookware directly from the oven onto the dinner table, place a mat or a trivet mat underneath as the cookware will be hot.
  • Some of the CorningWare bakeware products come with plastic lids that are not oven safe. 
  • Avoid placing the Cornware porcelain and ceramic cookware models under the broiler, toaster ovens, and microwave. They have a low ability to withstand thermal shock. 
  • Bowls, plates, mugs, and cups are made mostly from porcelain and glazed stoneware. Always preheat your oven before placing them inside. Do not use them inside the oven beyond 350 degrees Fahrenheit. 

Final Words

Corningware cookware is safe to use in the oven. Depending on the material used, it can be used safely in the range of 350 -500 degrees Fahrenheit. 

While the glass-ceramic models have a high heat resistance of up to 500 degrees Fahrenheit, the stoneware models can be used up to 350 degrees Fahrenheit.  

The Corningware cookware made of glass-ceramic has high heat resistance, has an excellent thermal shock ability, and can be used in the dishwasher.

You can take the cookware directly from the fridge to the oven to the tabletop. 

The Corningware models made from stoneware or porcelain are not resistant to thermal shock.

They need to be brought down to room temperature from the fridge before using in a preheated oven. 

The same goes for the glass lids of all the Corningware cookware. They need to be at room temperature and used in a preheated oven. Use them in an oven up to 350F. 

In the end, I would like to stress that it is very important to read your product manual and the instruction booklet before using your Corningware piece in the oven.

This way you will know about your product’s maximum temperature limits,  and if it is oven safe and broiler safe.
