Can You Put Glass In The Oven?

Can You Put Glass In The Oven?

Though it might seem ordinary to place a glass baking dish in the oven, even a slightly wrong decision in this situation could cost you more than just a mess. But don’t worry, it’s not that bad. 

If the glass is labelled as oven-safe, you can easily put it in the oven. Most of the glasses used for dishes are made of tempered glass, but non-tempered glass should never be used in the oven.

Therefore, it is wise to look at an oven-safe tag on your container and then use it because it would be dangerous to put any ordinary glass in the oven without verifying it. 

Now, you might be thinking of what dishes are made of tempered glass and which ones are not.

So without further ado, let us take a deep look into all the possible questions you may be asking yourself.


Are All Types Of Glass Safe To Use In An Oven?

Baking with glass might be a little challenging because not all glasses are oven-safe.

Therefore, you should look out for oven-safe and maximum temperature glass ranges.

For instance, you can turn over the container and look at the bottom for text or a symbol.

This symbol typically resembles a small oven and indicates whether it is secure to use in ovens.

However, some containers might not have the oven-safe label but that does not immediately imply that you can not use them for baking.

In such circumstances, finding the item’s composition can be of good use. 

Also, if you still are not sure about it, you can consult the owner’s manual or the packing.

These will frequently inform you of the type of material it is composed of, the product’s oven compatibility, and the temperature-safe ranges it can withstand. 

After looking at the composition, it would be easy for you to understand what should go in the oven and what should not.

For example, you can put the container in the oven if it is constructed of tempered glass or pyrex.

On the contrary, a non-tempered glass should never go in the oven

What Does The Term Oven-Safe Imply?

Simply put, cooking ware items that can tolerate prolonged exposure to oven heat are referred to as oven-safe.

The majority of the stovetop and cookware is oven-safe, therefore saving you bucks. 

However as a general rule, In the oven, kitchenware with plastic handles must be avoided.

Under extreme heat, plastic is more prone to melt and release harmful fumes that could contaminate your food.

So, you should always choose to bake with oven-safe cookware only.

What To Do In Case You Can’t Find The Symbol?

There are many cases when we don’t keep the packaging material with ourselves and sometimes the dishes also don’t have any symbol on them.

In such cases, it is suggested to do some research. 

If you know the product and the kind of glassware, then go for a short internet search to see if the product is oven-safe.

You must determine the type of material the pot or pan is made of because each one reacts to heat differently.

Look for a non-stick coating, and be sure to ask the manufacturer what temperature the non-stick cookware is best suited for. 

Safety Precautions That You Should Be Aware Of When Using Oven Safe Glass

Though it is safe to use tempered glass or pyrex in the oven, there are some precautionary measures you should take to save yourself from future damages. 

  1. Extreme Changes In Temperature

The first is the maximum recommended temperature.

Many glass containers available on the market today can survive drastic temperature changes, but the majority of them can not withstand abrupt temperature changes.

However, the average high-temperature glass can withstand 400° Fahrenheit. 

  1. Structural Flaws

Even if your pot is marked oven-safe, some structural problems such as tiny fractures might make the glass break in extremely cold or hot temperatures.

Even a minor scratch on the container can result in weakening and eventually breaking your container.

Therefore, you should check any glass dish for damage before putting it in the oven. 

Also, you should not put a glass container into a hot oven right after removing it from the freezer or refrigerator.

The glass will break if you do this.

Similarly, the dish should not be taken out of the oven and put right into the freezer or fridge

Pyrex Glassware

Can Pyrex Glassware Be Used In An Oven?

As stated earlier, all pyrex glassware is suitable for use in ovens. The oven must however, remain within the 450 degrees acceptable temperature range.

Despite this, pyrex glass containers must never be used in a cooktop application as your dish might break under direct heat. 

Are Mason Jars Safe To Use In An Oven?

As the use of pyrex is not prohibited, many people believe the same for mason jars as well. But you should never bake in mason jars.

Although they can tolerate boiling water, they are only temperate resistant to 212 degrees Fahrenheit. 

No matter how good it looks to bake in them, it is dangerous as they are prone to breaking, and also they do not distribute heat evenly, so your food will be partially cooked in some areas and not in others.

However, to some extent, you can only heat them in the oven to sterilize them. 

Final Words On Putting Glass into the Oven

Though it is safe to use some types of glasses in the oven, precautionary measures should always be taken.

Look out for the oven-safe symbol and if you can not find them, do some internet research.

Last but not the least, check out if your glass is tempered or non-tempered as non-tempered ones are not made for the oven.
