Can you put glass in the oven? Yes, you can, if it has been labeled as oven-safe. Placing glass that is not oven-safe or heat resistant inside the oven can cause it to break or explode. Read more.
Glassware meant to be used inside the oven is made from specially formulated glass or tempered glass that can withstand high temperature. Never should you use an ordinary piece of glass like a glass plate or glass serving plate inside the oven.
Most manufacturers place labels (usually found at the back) on glass indicating that it is oven-safe to eliminate the guess work. If the glass plate or casserole does not come with an oven-safe label the safest way to go is not to place it inside the oven. These are usually the vintage, antique or handmade glass as well as ordinary glassware.
Oven-Safe Glassware Precautions
Even if glass has been labeled as oven-safe there are certain precautions that you need to follow:
- Never allow oven-safe glass to get into direct contact with a heating element (burner or stove top burner).
- Never place oven-safe glassware in an oven toaster, grill or barbecue.
- Never use oven-safe glass in a broiler.
- Follow manufacturer’s guide on the temperature limit inside the oven.
- Prevent thermal shock.
Keep in mind these precautions to keep your glassware from cracking, chipping or breaking.
How to Prevent Thermal Shock
Thermal shock occurs when glass is subjected to sudden and significant changes in temperature even when oven safe or resistant to heat.
- Prevent oven-proof glass from getting in contact with water while still hot.
- Never pour cold liquids into hot glassware.
- Avoid placing hot glassware from the oven onto granite countertops. Place it atop a dry hot pad, pot holder or towel.
- Never place glassware directly from the freezer to a pre-heated oven.
- Avoid placing hot glass into the dishwasher.
These scenarios will cause glass to break even if it is oven-safe.
Cooking using Glass Bake ware
Most manufacturers recommend not heating oven-safe glass higher than 3500F. It is also recommended that you reduce the temperature by 250 10 minutes before the cooking time is over and check for doneness.
It can take some time for glass to heat up but when it does it will get to be very hot. When hot, glass does not quickly cool. While still hot prevent any liquid from getting into direct contact with glassware.
When cooking with oven-safe glassware, make sure it is in top shape. Never use glassware in the oven when any of these conditions are present:
Glassware with a chip or scratch will tend to expand when inside the oven and will eventually break with all your food splattering inside your oven.
Even without noticeable cracks, chips or scratches, glassware that has been struck heavily by cooking utensils, bumped or dropped will cause it to weaken and break while heating inside the oven. It is best to discard glassware that has been subjected to these kinds of torture.
Can you put glass in the oven? Of course you can as long as they are labeled as oven-safe and necessary precautionary measures are followed.
How do I know if my glass is oven-safe?
Some glass containers are oven-safe while others are not. Most oven-safe containers have a symbol located on the bottom.

Yes, glass is almost always microwaved safe. If you get a new piece of glassware that isn’t specifically marked as microwave safe, try using the steps we provided to quickly test the container.
At which temperature does glass break?
When heated, thin glass begins to crack and typically breaks at 302–392°F. If a glass container is placed on a very hot source of heat (e.g., 500°C), it can gradually lose its shape and change from a permanent solid form to a plastic state. In general, glass jars should not be heated in a microwave or oven.
Can Mason jars go in the oven?
Can I put my Mason jar in an oven? No. Keep your Mason jars out of the oven. Kacey Christian from the National Center for Home Food Preservation says that oven processing times are inaccurate, the temperature fluctuates too much, the oven’s dry heat is unsafe, and the jars are much more likely to shatter.
Does glass explode when heated?
When Can Glass Shatter from Heat? Glass is a durable material that stands up well to summer heat. Indeed, the glass on your car helps to shield you from one hundred degrees plus weather. However, Glass can suffer a thermal break when the temperature gets too hot.
Why does Pyrex break in the oven?
When a Pyrex bowl is heated or cooled rapidly, different parts of the bowl expand or contract by different amounts, causing stress. If the stress is too extreme, the bowl’s structure will fail, causing a spectacular shattering effect.

Can I bake in Pyrex at 450?
Pyrex is meant to be able to withstand higher temperatures. But everything has its limitations. Pyrex can be used safely inside an oven that is less than 450 degrees F. Whether or not it’s inside a conventional oven or a convection oven, this glassware will be safe to use so long as that temperature isn’t exceeded.

Even though glass is generally microwave safe, microwaving cold glass is out of the question. Chilled glass will break or shatter when exposed to extreme temperature fluctuations in a high heat microwave.
Can you put glass on the stove?
Glass, even tempered glass is fairly rigid and doesn’t conduct heat like metal, therefore it’s subject to what’s called thermal shock. If the glass is exposed to uneven temperature extremes, it will try to expand or contract unevenly and can crack or shatter.

Can window glass break from cold?
Typically, remarkably cold weather can cause thermal stress cracks or pressure cracks in your home’s windows. This particular kind of stress crack usually starts small near the edge of the window, slowly continuing to spread across the glass. The reason for this is due to extreme fluctuations in temperature.
Does glass expand in cold?
When we heat up glass that has a high coefficient of thermal expansion, the glass expands. If it is then placed against something much cooler like a metal sink or stove top, the part of the glass touching the cooler object cools faster than the rest of the glass.

Can I heat up glass?
Heat Polishing Glass
When you heat glass to a temperature of 1300 to 1350 degrees F, the surface of the glass becomes soft enough to just start to melt. By heating to a point where just the very surface of the glass reaches this temperature, you can produce a smooth, shiny effect.
Does glass explode in a fire?
A fire will not ignite glass. However, glass can melt even if it doesn’t boil, though it won’t burn. The melting point is around 1400 degrees to 1600 degrees Celsius, or about 2,900 degrees Fahrenheit.
Can hot water crack glass?
The effect of thermal shock is powerful and results in the cracking of glass. Even heat-resistant glasses like Pyrex can shatter when poured with boiling water incorrectly. To prevent the glass from cracking when exposed to boiling water, you should avoid extreme and abrupt changes in temperature.
How do you stop Pyrex from exploding?
- Don’t set a hot glass dish directly on the metal eyes of your stove.
- Don’t cook a dry dish in a glass pan.
