Can you put glass in the freezer?
Both yes and no.
Glass can be placed in the freezer under certain conditions, but storing some types of glass in it can be harmful if proper precautions are not taken.
The problem with incorrectly placing glass in the freezer is that it can break. If you've ever come across this, you've probably wondered what's going on. Many factors could have caused your glass to crack. In the next section, we will go through these possible reasons.
Does glass break when it freezes?
Yes, frozen glass can break, but usually not. If you open the freezer and find that your glass is broken, the following factors may be to blame:
- The glass was way too hot.
- The glass was not tempered.
- The glass could not be frozen.
- The glass has been overloaded.
- The glass was very thin.
Does glass break in the freezer?
Now that you are aware, let's take a closer look at each of the reasons glass can break in the freezer.
The glass was too warm
It is not a good idea to put a hot or warm glass in the freezer due to the risk of thermal shock. The temperature difference will cause the glass to expand and shrink too quickly, causing frozen glass to explode!
The glass has not been tempered
Tempered glass is much more durable than regular glass. As a result, this glass is far less likely to shatter when subjected to the pressure of frozen food or liquids.
The glass was not suitable for freezing
You've probably heard of microwave and oven safe glass, but did you know there's also freezer safe glass? That's right. Just look on the packaging, label or bottom print of the jar you want to freeze.
There was too much pressure in the glass
When glass contents freeze, they often expand. This is especially true for liquids. This pressure builds up on the edges and top of your glass, eventually breaking it if it's not sturdy enough to support it. Therefore, we recommend using tempered or freeze-proof glass.
The glass was too thin
This ties in with the last tip, but freezing a jar that's too thin will almost certainly cause it to explode. This is due to the pressure exerted by the contents of the jar.
How long can you put glass in the freezer?
Glass can be kept in the freezer forever, but that only applies to freezer-safe glass. Additional glasses can also be stored indefinitely in the freezer. Unfortunately, we cannot be certain that this will be the case. The answer depends on the type of glass used.
How can you tell if glass is freezable?
There is usually a mark or phrase on the bottom of the jar that indicates whether or not it is freezer safe. If not, check the packaging or search the product online to learn more.
If you are not sure, we recommend that you do not put it in the freezer.
Types of glass in the freezer
Below are some examples of glass that you may want to freeze. How will they fare in the face of the intense cold?

Can you put a drinking glass in the freezer?
A drinking glass can be placed in the freezer, but chances are it will break if left there. Drinking glasses are often made of thin glass, but this is not always the case.
If you need to keep it there for a short time, make sure it's at least at room temperature and that you don't leave it for more than 30 minutes.
Can you put pyrex glass in the freezer?
Is it safe to put glass pyrex in the freezer? That's an excellent question!
Pyrex has multiple uses including use in ovens and microwaves. Luckily it can also be used in the freezer as long as the pyrex is not heated when placed there.

Can you put wine glasses in the freezer?
If your wine glass is untempered and not labeled freezer safe, you can place it in the freezer for a short time.
Start with 30 minutes to an hour. If the jar is empty, you might be able to keep it there longer.
Beer glass in the freezer
It's perfectly fine to chill or freeze an empty beer glass in the freezer.
Even so, it's usually not advisable to freeze your beer bottles. It can change the taste of the beer and the bottle can burst.
Can glass Tupperware go in the freezer?
Glass Tupperware marked Freezer Safe can be stored in the freezer and will help keep odors and freezer burn at bay!

Can you freeze glass bottles of milk?
We do not recommend storing milk in bottles as it expands when it freezes. This can break the glass.
Can you freeze glasses?
Several types of glass jars can be frozen if they are labeled freezer safe.
Can you freeze a mason jar?
Most mason jars are freezer safe, but check the manufacturer's directions to be sure. It has also been suggested that wide-necked mason jars with no shoulders are preferable for freezing because they do not stress the jar as much as traditional mason jar shapes.

Can a glass bowl go in the freezer?
Glassware can be stored in the freezer. Just make sure they're freezer safe before putting them in there. Also keep in mind that certain glass bowls can cause more freezer burn than others, especially if they're not labeled freezer-safe.
Can glass pans go in the freezer?
Some types of glass pans that are suitable for oven and microwave use are also suitable for freezer use, but you should check the product specifications to be sure.
Glass in the freezer is safe... most of the time!
In most cases it is safe to put glass in the freezer for a short time. However, if your jar and its contents completely freeze over, you may be in danger. To be on the safe side, only store glass in a freezer that is marked as freezable for long periods of time. Otherwise, the glass may shatter or splinter.

FAQ
Does glass break in the freezer?
Some types of glass can shatter in the freezer. It depends on the content and the type of glass.
Can you put glass in the freezer overnight?
Only put jars marked freezable in the freezer overnight. Otherwise it's a bad idea.
How long can you put a glass bottle in the freezer?
A freezer-safe glass bottle can be kept in the freezer forever. But if it's not freezer safe, we don't recommend freezing it for longer than 30 minutes. Glass bottles, especially narrow ones, tend to break from pressure build-up.
Can you put a jar in the freezer?
A single glass in the freezer can be safe. If you're not sure if it's safe to put it in the freezer, don't put it there for more than 30 minutes or an hour to avoid cracking.
You certainly can! Not only can glass containers be frozen, but they're also a great eco-friendly option. Because glass isn't porous like plastic, it doesn't discolour or absorb odors.
Can glass shatter in the freezer? Glass can break in the freezer, as some of us have found. This only happens when the bins are overfilled or packed too tightly together. The key is to leave plenty of room at the top of the jar.
Freezing mason jars is an excellent technique for preserving foods, soups, and condiments! Make the most of your food stash by putting it in the freezer. Food, spices and beverages can last significantly longer when stored in mason jars with lids. They are airtight and will prevent freezer burn if stored properly.
How long can you keep a jar frozen? From everything we've mentioned so far, you can keep an empty jar in the freezer for as long as you need to. Make sure that the glasses are not exposed to sudden changes in temperature.
What causes mason jars to crack in the freezer? Untempered glass has small air pockets that expand and contract as the glass is heated and cooled, particularly at the high temperatures used in canning and freezing. If the tiny air bubbles spread, the glass will break or even explode!
When a standard float glass window pane is first heated, it breaks at a temperature of around 150-200°C. The initial break starts at one of the edges.
Glass, especially the set from OXO, convinces with the storage of food in the fridge or freezer. The containers are freezer safe to prevent glass breakage, leak proof and tightly sealed (no weird substances clinging to your fridge shelves!) and easy to clean.
Tempered glass is marked with a mark in the corner of the glass pane. The label includes the name of the manufacturer and CPSC (Consumer Product Safety Commission) regulations such as: e.g. "CPSC 16 CFR 1201 CAT II". This determines whether or not the glass has been tempered.
Pyrex® invented COOK&FREEZE, a collection of heat-resistant borosilicate glass ovenware that allows you to safely go from freezer to oven and oven to freezer to prepare for a busy week's meals or freeze leftovers. COOK&FREEZE is designed to withstand a temperature shock of 220°.
Freezing mason jars is an excellent technique for preserving summer vegetables and other foods. Still, it's important that you adhere to some basic best practices. Fill Mason jars halfway because food expands as it freezes. As it grows, pressure can build up in the glass and shatter the glass.
