Pyrex was invented in the United States in 1908. It was more resistant to thermal stress than other types of glass.

Nonetheless, the production method has evolved. Before, borosilicate glass was utilized; however, soda lime is now used, and the result is not as strong.

Thermal shock is not a problem with today’s pyrex dishes. As a result, if they were transported from one extreme temperature to the other, they would shatter.

Nonetheless, pyrex plates may be used for regular baking.

Can Pyrex Cookware Be Used in the Oven?

The simple answer is yes. Pyrex glass may be used in the oven for cooking and baking.

But, keep in mind that using pyrex on your cooktop is a poor idea. You should also avoid moving the pyrex pan from one extreme temperature to the other.

Thermal shock has occurred, and the pan will most certainly break as a consequence.

Pyrex’s Temperature Capacity

As a general guideline, just heat the pyrex pan or dish in the oven to 400-450 F.

Anything greater than that may significantly compromise its structural integrity.


Your pyrex dish has its limitations. Note that you may only move it from the fridge to the freezer, then to the oven in short bursts.

Other than that, here are some additional limitations to be aware of.

  • Preheat the oven before adding the pyrex plates. Heat exposure should be kept to a minimum.
  • Never use pyrex on your stove, toaster oven, or grill.
  • Let the pyrex to cool before returning the hot dish to the fridge or freezer.
  • Let the pyrex pan to cool before adding liquid.
  • Do not microwave popcorn or cook food in browning wrappers in Pyrex.
  • Empty glass containers should not be microwaved.
  • Don’t overheat cheese, oil, or butter in a pyrex pan in the microwave. Heat for the shortest amount of time possible.


Examine the guarantee that comes with your pyrex dish or pan. There are frequently stipulations that allow you to replace damaged plates or pans caused by oven heat.

You should definitely verify this warranty before purchasing the dish as a precaution.


  • Wear closed-toed shoes if you’re cooking with pyrex. This will prevent glass from getting into your shoes or cutting your feet if it breaks.
  • Use strong gloves while cleaning up the glass. This will keep your hands safe.
  • While picking up fragmented fragments, take extreme care. Little fragments might enter your eye or harm your skin.
  • Throw away any food that was in the pyrex dish when it shattered. Small fragments may get embedded in food. It is futile to clean the meal of any fragments. Even little bit of glass entering your body isn’t worth the world’s most wonderful cuisine.

Keep in mind that these precautions and warranties only apply to pyrex cookware and plates.

These are not applicable to the pyrex pan covers. Only microwave heating and storage are permitted with the covers.

Using Pyrex Dishes Safely

Although being a very well-made tempered glass, Pyrex may readily fracture under the correct circumstances. As a result, you must know how to handle pyrex glass professionally.

So here are a few steps you may take to avoid injuring yourself. They will save you from getting burnt, cut, bruised, or hurt in any manner.

  • Preheat an oven sheet pan in the oven. Next set the pie dish or pyrex pan on top. This will disperse the heat evenly around the pan without putting pressure on it.
  • Never place a hot pyrex glass pan on a cold surface, or a cool pyrex glass pan on a hot surface. Both will cause heat shock to the pan. Very likely, the pan will be broken as a consequence of this.
  • Before placing the pyrex glass on the burner, place it on a silicone or fabric heat pad. This will keep it from breaking.
  • Use a dry dish towel or a wooden cutting board on a countertop before placing the pyrex pan. This keeps the pyrex pan from sliding and dropping.
  • Avoid cooking a dry food in a glass pan. Instead, pour a little amount of liquid into the dish to cover the bottom before adding the dry food. This prevents the heated glass surface from coming into touch with the dish’s cold fluids. As a result, a surface between the two will prevent the pyrex from receiving heat shock.
  • While touching the pyrex dish, use dry mitts or towels. This will keep the pyrex dish or pan from breaking in your hands due to heat stress.
  • When cleaning the pyrex pan, make sure it is dry and at room temperature. This is done to prevent heat shock.
  • When reheating dry meals in the microwave, avoid using pyrex pans. As a general guideline, avoid using Pyrex pans to cook anything in the microwave. This will compromise its structural integrity. If not, the structural integrity of the glass will most likely be compromised.

Pyrex substitutes

All of these dishes are accessible to beginners to use instead of pyrex glass.

Some people may not have access to glasses, while others may be just getting started. As a result, they may need something that they have on hand that they can work with.

Not to fear, one of them may already be in your kitchen.

Casserole Recipe

Casserole dishes and Pyrex glass dishes may be used interchangeably. If the dish is deep enough and the lid fits securely.

You will also need to sauté or brown the meat in a frying pan before placing it in the casserole.

This additional step is necessary because a casserole dish cannot be heated over an open fire. This is when the casserole dish resembles a pyrex dish.

The Clay Pot

When it comes to heating, clay pots function similarly to any tiny oven. As a result, they may perform the same functions as a pyrex dish.

As the liquid evaporates, it slips down the back of the dish. This is ideal for self-basting and turkey cooking. Nevertheless, it is not suitable for making cakes.

The clay pot’s cover design enables steam to rise when the food is cooked.

The moisture condenses on the lid and falls back down. This is known as taking use of the concept of convection.

Since glazed clay pots are now manufactured, great care must be given while selecting a heat source. An open fire is not an excellent source of heat. An oven, on the other hand, is.

Pot made of metal

Metal pots are an excellent substitute for glass pyrex pans. They absorb heat significantly faster and hold it for far longer than pyrex pans.

But, always check the directions to see how much heat they can withstand. When it comes to the manufacturer, this might vary greatly.

Pot made of ceramic

Soups and stews are ideal for cooking in a ceramic pot.

Therefore, it cannot be used in place of bakeware. It is capable of melting chocolate and combining other substances over a low heat.


A stockpot with a tight-fitting cover works well in place of a pyrex pan. You may use it to sauté, sear, and bake.

To prevent sticking, just do it over low heat. You must use low heat and monitor the liquid level on a frequent basis.

You may use the same baking procedures as you would when using a pyrex pan.

Soup Maker

The soup pot will function similarly to a stockpot.

But keep in mind that you will need to make certain adjustments to various recipes.


Braisers can cook almost anything that can be fried or baked. The key distinction is that the circumference of the pot’s sides is significantly different.

If you have a braiser, you can adapt recipes to it with a little creativity.


Skillets are ideal for sautéing or searing. You may also use it to cook various foods if necessary. A skillet roast may also be cooked in the oven.

Slow cooking and stewing, on the other hand, are not possible on a skillet. There is no cover, so you must improvise there as well.

Cooking Pan

Frying pans, like pyrex glass dishes, need a cover to function properly. As with other appliances, this pyrex glass dish alternative enables you to sauté and sear in the pan.

You may add any ingredients you want and cook them whatever you like.

Pan for Roasting

A roasting pan is an excellent substitute for a pyrex glassware dish. The pan should be used in the same manner as a frying pan is.

You may safely use your pyrex dish or pan in the oven if you follow these measures.
