See If Glass Can Go In The Oven + Safety Rules To Follow

Can you put glass containers in the oven? Is it safe to do so?

Here is your answer: you can put glass in the oven if it is oven-safe. If you are not sure whether glassware is oven-safe, save yourself a lot of trouble by not putting it in.

Asides from the cupboard, the oven and microwave are other places many things go into. Unlike the cupboard that can take anything, the oven and microwave do not work that way.

In this article, you’ll be getting answers to your questions about the safety of putting glass containers in the oven.

Can glass go in the oven?

Not all glassware is the same. Only oven-safe glass can go in the oven.

Generally, glass is an insulator, not a conductor. So, when it is under heat with water or food in it, the content stretches and stretches the glass too.

Under rapid temperature fluctuations, glassware that is not oven-safe will crack. So, if you want to heat food in the oven, look under the glassware and be sure it is oven-safe.

In addition, do not heat the glass beyond its temperature limit.

Can you put cold glass in the oven?

Some glassware can go straight from the refrigerator or freezer into the oven.

These glass containers are thermal shock resistant and can withstand rapid temperature changes. However, doing this repeatedly will shorten the lifespan of the glass.

Allow the glassware to come to room temperature on the kitchen counter before putting it in the oven.

Can Pyrex glass go in the oven?

Yes, you can put Pyrex glass in the oven.

Pyrex is one of those companies that make oven-safe glassware. You can put this glassware in a preheated oven.

Moreover, it is safe for warming, cooking, and baking food in a pre-heated conventional or convection oven.

Can borosilicate glass go in the oven?

Yes. Borosilicate glass is heat and thermal shock-resistant.

You can safely put it in the oven even while it is cold. The glass can be heated up to 392°F to 446°F. Also, these glasses have a low thermal expansion, they do not easily shatter in the oven.

Can tempered glass go in the oven?

Yes, you can put tempered glassware in the oven.

Tempered glassware can withstand high oven temperatures. They are thermal shock resistant and do not easily shatter in the oven. However, it is not as heat-resistant as borosilicate glass.

Can microwave-safe glass go in the oven?

Yes. A microwavable glass is also oven-safe. You can use your microwave-safe glassware to cook, reheat or bake in the oven.

Can IKEA glass go in the oven?

IKEA glass food containers are made with oven-safe materials. You can reheat, cook or bake food in these glass containers.

Can Marinex glass go in the oven?

Yes, Marinex glassware can go in the oven.

You can use this glassware to cook, reheat, and bake food in both conventional and microwave ovens. However, you must be sure that the oven does not exceed 212°F to start.

In addition, the glassware can go from the freezer to the oven if you do so correctly.

Can you put glassware with the lid in the oven?

Yes. Like glass containers, an oven-safe glass lid can go into the oven.

Covering your meal while it cooks in the oven will give you a well-cooked and tender meal.

What temperature can glass go in the oven?

Oven-safe glassware can go in the oven at any of these temperatures: 200°F, 275°F, 350°F, 375°F, 400°F, 425°F, 450°F, and 500°F. However, 500°F is the limit, the strain point for most glassware.

Additionally, these temperature limits vary with different glasses. Therefore, you should know the temperature limit of your glassware before putting it in the oven.

How do you know glass is oven-safe?

1. Check for the oven-safe symbol

Oven-safe glassware has a symbol that shows that you can put them in the oven. There are different oven-safe symbols. It could be a bowl with steam in a box or a pan in an oven.

2. Visit the manufacturer’s website

If you don’t see the oven-safe symbol on your glassware, visit the manufacturer’s website for the necessary information.

You can also check the user guide that came with the glass. Look for information on the type of material the glassware is made of. If it’s borosilicate or tempered, it can go in the oven.

3. Check for metallic components

Glassware has metallic handles, bottoms, or paintings is not safe. Metal and glass expand differently under heat. And the expansion coefficient of metal is higher.

Also, the thermal shock resistance difference between both materials can trigger breakage.

Why does glass break in the oven?

Glass may shatter in the oven for any of the following reasons:

1. Rapid temperature change

Frequently taking cold glassware directly from the refrigerator or freezer and putting it straight in the oven will make it break.

Always allow the glass to come to room temperature before putting it in the oven.

2. Putting the wrong glassware in the oven

When you reheat, bake or cook food in the oven with the wrong glassware, you risk losing your container.

Moreover, setting the oven at the wrong temperature for the glassware can shatter glass. Generally, you shouldn’t heat any glassware beyond 450°F.

3. Heating damaged glassware in the oven

Chipped or cracked glassware will break in the oven. At high temperatures, these weak areas become weaker and eventually break.

How to prevent glassware from breaking in the oven

  • Preheat the oven before putting the glassware
  • Use the right glass containers. Go for Pyrex, tempered, quartz, or borosilicate glassware
  • Examine the glassware for cracks and chips. If any, do not put the container in the oven
  • Do not change the cooking temperature drastically
  • Also, do not exceed 500°F
  • When baking or warming dry foods, add water to the bottom of the container
  • In addition, allow the glassware to cool on a cooling rack, not on a wet or cold counter
  • Also, do not put the glassware directly under the grill of a toaster oven
  • Most importantly, follow the instructions in the user guide for the oven and glassware


How hot should glass get in the oven?

Glassware can get as hot as its temperature limit. Ideally, it shouldn’t go over 450°F; otherwise, you risk shattering the glass.

Can you bake a cake in a glass dish?

Yes, you can bake a cake in a glass dish.

If you do it correctly, you’ll end up with a nice cake. If the recipe says you should bake at 450°F, lower it by 25°F. This means you should bake the cake at 425°F.

While you bake, keep an eye on the cake to prevent browning and uneven baking.

Will oven-safe glassware explode in the oven?

Yes, even oven-safe glassware can explode in the oven if you don’t handle it properly.

When the glass comes in contact with high temperatures or rapid fluctuation, the glass will experience thermal shock and explode.

Can you take a frozen glass baking dish and put it in the oven?

If you’re talking about Pyrex glass, yes, you can.

The manufacturers state on their website that you can take a Pyrex glass frozen from the freezer and put it in the oven at 300°F.

However, doing this constantly at frequent rapid temperature changes can shatter your glassware.

The best way to do this is to allow the frozen glassware to thaw in the refrigerator before placing it in a preheated oven.


So, can you put glassware in the oven? Yes, if you’re using the right glass. There are different types of glass, and each type handles heat differently.

Check the bottom of the glassware for the oven-safe symbol. Do not use the glass, if it’s not oven-safe.

Remember that the wrong glass in the oven will get damaged. Also, keep chipped or broken glassware out of the oven.
