Can Glass Go in the Oven?

The simple answer is yes, glass can go into the oven, however, it may depend upon your specific type of glass dish, what the dish is made out of, and what type it is. It can also depend on if there are any flaws in your container and the temperature of your oven. Don’t worry, we will take a deep dive into each one of these below. 

There are many different reasons why you might want to cook with glass. Glass dishes are a toxic-free baking dish, and are usually see-through and allows you to see how your food is cooking. Plus, after the food’s cooked the glass allows you to store it in it as well, making only a few dishes for you to clean up. 

How can you tell if the glass is oven-safe?

There are a few different ways you can tell if your glass dish is okay to put in the oven. Most glass bakeware with lids and glass baking dishes, such as Pyrex bakeware or Anchor Hocking casserole dishes are specifically made to withstand heat.

One of the main ways you can tell if your glass dish is okay to put in the oven is to look for an oven-safe symbol on the pan. Usually, you can find a symbol, or oven safe listed on the bottom of your baking dish if it is appropriate to put in the oven.

Check the User Manual

Another way to tell if your dish is okay to put in the oven is to look at your packaging or user guide. Both of these should state if the pan is safe to be put into the oven. 

Type of Glass

What type of glass your dishes are made of can also determine if it is safe to use in the oven. Glasses such as tempered and borosilicate products are alright to use in the oven. These types of glass should have oven safe symbols on the baking dishes. 

At What Temp Does Glass Break

The temperature at which glass may break depends on what type of glass it is and how quickly it is heated. For example, if you add a cold dish to a warm oven it is likely to break right away no matter what kind of glass it is. Glass, in general, does not handle rapid heat well and will break.

On average, the information below will show you at what temperature different types of glass may break. 

Pyrex Glass 425°F or above

Tempered Glass 470°F or above

Borosilicate Glass 330°F or above

Looking at these different temperatures, you may realize that regardless of the glass you are going to cook with, you may want to be sure to only bake with glass when making your food at lower temperatures. 

Can You Put Cold Glass in the Oven

Glass reacts badly to a quick change in temperature, it is not a good idea to move glass baking dishes such as Pyrex from your fridge to the oven. When you do this, it greatly increases the chance that your dish will break in the oven. 

Rather than moving your cold glass dish directly from the fridge to your oven, it’s a good idea to allow your dish to warm to room temperature before placing it into the oven. Even then, you should put your dish into a cold oven and heat your oven with the dish inside of it.

What Can Cause Glass to Break in the Oven?

There are many different things that can cause glass to break in your oven. This ranges from your dish being old, or flawed when it is put into the oven, all the way to a quick temperature change from cold to hot. For details, let’s look at what can cause the glass to break in the oven. 

Drastic Temperature Changes. When glass encounters a significant temperature change it is much more likely to break because of the quick change. 

The Wrong Type of Glass. Another reason why your dish may break in the oven is that it should not be put into the oven, to begin with. Basic types of glass have much lower heat resistance and will break usually in the oven.

Typically dishes that are made for bakeware do not break easily, however, if you try to put glass in that is not intended for the oven, such as plates, bowls, or glasses, they are likely to break easily. 

Temperatures That Are Too High. Another reason your glass may break when heated is that the temperature is too high for the type of glass. Because of this, it is a good idea to avoid putting these dishes in an oven at a high temperature. 

Check for Cracks or Scratches. Another reason why your glass may break in the oven is that the dish has scratches or cracks in it. This causes structural weaknesses in your glass dish and may cause it to break when heated.

How to use Oven-Safe Glassware

  1. Make sure your dish is at room temperature before adding it to the oven.
  2. Place your room temperature glass baking dish into a cool oven and then turn it on to preheat once your dish is added.
  3. Bake your food in your dish for a longer amount of time if needed at a lower temperature. If using Pyrex dish then make sure your temperature is 425°F or below or four tempered for 470°F or below. 
  4. After your food is baked and your dishes are removed from the oven, allow your dish to cool to room temperature before rinsing in water. Yes, washing a hot glass dish and water can also cause the dish to break. 
  5. If you are placing your dish in the fridge for later, make sure your glass dish cools to room temperature before placing it into the refrigerator. 
  6. The same also applies if you are placing your glass dish into the freezer. Make sure your glass baking dish cools to room temperature before placing it into the freezer. If possible, it’s a great idea to let your dish cool in the fridge for a few hours before freezing it as well.  
  7. When baking dry foods in glass it is a good idea to add liquid to the bottom for dry foods. This will help prevent your dish from baking in the oven as well.  

What To Do if Your Glass Breaks in the Oven

What if your glass dish does break when it is heated. Well, to start with you are likely to hear a very large explosion come from your oven. This sounds like someone is breaking into your house or setting off a bomb.

When you hear this sound, do not rush in and try to clean up the mess right away. Rather turn your oven off and keep the oven door closed. Let the glass cool off completely before you try to clean it up.

Very carefully pick up any large pieces of glass in your oven and throw them away. Then try to pick up the smaller pieces very carefully. If you have a vacuum that can handle small pieces of glass, you can use this to clean out your stove as well. 

The bottom line, if you have to clean up broken glass in the oven, be extremely careful that you do not cut yourself. Also, wait for the glass to fully cool before you try and touch it.
