When cooking for a large group or just yourself, you may run out of cooking pots and prefer to rely on less standard cookware such as glass.
You may be afraid to cook with a glass pan because you’re afraid of your glass container shattering in the oven.
In this blog post, we’ll look at whether you can put glass in the oven.
Can You Put Glass in the Oven?
Yes, if your glass is oven-safe, you can put it in the oven.
Other forms of glass in your kitchen, such as drinking glasses and glass containers, are not intended for use in the oven and should be kept away from excessive heat unless identified as oven safe.
Annealed glass (ordinary glass) should never be used in an oven because of its limited structural strength and ability to withstand only mild temperatures.
Tempered Glass is more rigid, heat resistant, and durable than annealed glass.
Type of Glass That Can Withstand High Heat
Any heat-resistant glass can accommodate high temperatures. Below are the two main types of glasses that can withstand heat.
Tempered Glass is robust and resistant to heat whereby it goes up to 450 degrees, and it is meant to withstand drops or knocks to the glass.
Tempered Glass is stronger than untreated glass due to its increased surface compression.
Less likelihood of breaking when dropped sounds excellent, but there is a catch.
If tempered glass breaks, it will shatter into tiny fragments that can be pretty difficult to clean up.
Fortunately, the glass pieces have fewer sharp edges than other types of glass, which can help lessen the risk of getting wounded by a piece.
The most heat-resistant glass available for use in cookware is borosilicate glass. This glassware is designed to withstand greater temperatures as well as temperature fluctuations.
This cookware is frequently thin, durable, and safe for cooking and baking in most ovens.
What Makes Glass to Break in the Oven?
Yes, you may use glass in the oven. Yet, there are times when you use glass in your oven, and it will shatter.
So, what causes it to shutter?
Extreme Temperature Change
Temperature shock is the most common cause of oven glass breakage. Glass is not meant to endure frequent and rapid temperature reductions.
Temperature shock happens when there is a quick temperature shift, such as shifting from a freezer or refrigerator to a preheated oven.
The glass container can either expand or compress due to the sudden temperature change, which may cause it to shatter.
Let your glass containers get to room temperature before putting them in the oven to reduce the temperature difference.
Take your container out of the fridge, leave it on the counter for 10–15 minutes before using it in the oven.
Temperature shock can occur in various ways, therefore avoiding abrupt temperature change.
- From the refrigerator to the oven
- Moving from the oven to the refrigerator
- Putting a hot beverage in a chilly dish
- Putting a hot plate in a cold bath
Remember the requirements listed above, and you’ll avoid having to clean up broken glass.
Using the Wrong Type of Glass
A poor choice of glass can also cause glass shattering in the oven.
You now know that you may use tempered glass and borosilicate glass in the oven without breaking; however, the non-tempered glass will most likely break.
There should be no problems in the oven if you use the proper oven-safe glass.
It’s critical to examine your glass cookware regularly, especially before using it at extremely high temperatures.
Any cracked or chipped places in the glass are weak spots that are more prone to shatter when the temperature changes.
Any glass pan with cracks or chips should not be used in the oven, regardless of size.
Oven Temperatures That Are Too High
Even though the glass is labeled as oven-safe, you need to consider the oven’s temperature.
Some glass may be alright in the oven at specific temperatures, but it becomes dangerous as the temperature rises.
Typically, the manufacturer will provide a maximum temperature that should never exceed for safety reasons.
If you’re unclear of the limit and can’t find it online, it’s advisable to keep the temperature below 400 degrees.
How to Prevent Your Glass From Breaking in the Oven?
When your glass container is heated in the oven, it’s not difficult to protect it from shattering. You only need to take a few precautions to correctly cook your meal in a glass.
Don’t Make Sudden Temperature Changes.
The majority of glassware is prone to thermal shock.
Instead of moving from freezer to oven, go from room temperature to preheated oven. While you may be accomplishing this without any difficulty, you place your glass at risk of breaking.
When removing the glass from the oven, the exact science applies. Due to thermal shock, avoid placing the hot glass on a cold surface.
Alternatively, like hot pads, set it on a room temperature surface.
Make Use of Tempered Glass.
Again, not all glass may be placed appropriately in the oven unless it has been tampered with or has the indication “oven-safe.”
Manufacturers will typically mention temperature limitations for oven-safe glassware, so ensure you keep to them.
It would be best not to place drinking glasses and smaller dishes in the oven because they cannot withstand high temperatures.
The same principle applies to glass lids unless they are labeled oven-safe.
Avoid High Temperatures
Glassware, as previously stated, can resist a specified temperature limit. As a result, keep the specified higher limit in mind while using oven-safe glass.
This might be anything between 350 and 500 degrees. By remaining below the limit, you will extend the life of your glass.
Look for Structural Problems
We frequently do not check for defaults before using kitchen products. When using glass cookware, always examine it for cracks or even scrapes.
Cracks and scrapes indicate weak places that might easily shatter when extreme temperature changes.
Add Liquids to the Bottom of the Container For Dry Foods.
This method is most commonly used when baking.
Consider adding a small quantity of liquid to the bottom of the container when you’re baking dry goods.
As the dry food cooks, it releases part of its water content, which finally makes its way to the surface of the glass. And since the water may be cold, the glass will be subjected to thermal shock.
By adding tiny amounts of water to the bottom of your container, you will allow the water to warm up the glass while it cooks.
Why is Heating in Glass Containers Better?
So far, you’ve learned that glass is relatively safe to use in the oven. However, something remains unclear.
Why do people continue to heat in glass containers? Some of the reasons are listed below.
Glass is non-toxic; this is the most crucial reason heating with glass is better.
Other materials, in most situations, will have non-stick surfaces that are known to emit toxins.
Since scientists are experimenting with techniques to eradicate toxins, one of the suggestions they give us is glass. That is why you should cook with glass.
Preserves Heat Longer
Everyone desires to complete tasks as quickly as possible.
On the other hand, glasses have lengthier heating periods, which might be inconvenient.
However, glasses may hold heat for more extended periods. As a result, most individuals utilize glasses as serving dishes to keep their meals warm for extended periods.
A Clear Surface
Who wouldn’t want to see the ingredients in the cuisine they are preparing?
Other bakeware kinds make it challenging to see what you’re baking since the surfaces aren’t transparent enough to see what’s within.
This is a disadvantage since it is difficult to know whether or not your food is ready.
Simple to Clean
You can’t avoid washing and cleaning kitchenware regularly.
Glasses are more easily cleaned than other materials. Because glass is non-porous, it makes washing them more manageable.
Advantage of Storage and Reheating
Unlike other types of cooking equipment, you may use glass cookware to store food.
The only thing you need to do is make sure the meal has completely cooled before storing it.
You have the option of storing your meals in the fridge or freezer using glass cookware. The best part is that you can reheat the dish in the same glass pan.
Frequently Asked Questions
How Can You Tell If the Glass is Oven-Safe?
You can tell if your glass is oven safe by checking the bottom of your container for a symbol. Tempered Glass is always safe to use in the oven; however, you should never use non-tempered glass in the oven.
Look for the symbol as well as the temperature recommendation on your container.
Is it Safe to Put a Cold Glass Dish in the Oven?
You may put cold glass in the oven, but you must take specific measures. Ensure that your glass is heat-resistant.
It would be best if you also avoided excessive temperature variations. A quick temperature shift might cause the glass to shatter.
Glass is beneficial not just for baking but also for cooking and warming food. However, you should be mindful of the sort of glass you are using.
Because various glasses have varying temperatures, you must ensure that you use the correct glass for the right purpose to avoid breaking.
