5 Key Tips To Keep Glass From Breaking In The Oven

Read this article of BestLifeTips to find out can you put glass in the oven and how to keep glass from breaking in the oven.

While cooking in the oven, you may wonder can you put glass in the oven. In this article, BestLifeTips will talk about this topic and how to keep glass from breaking in the oven.

Can you put glass in the oven?

The answer to “Can you put glass in the oven?” is yes, you can put glass in the oven.

Generally, glass is oven safe if taken from room temperature and put in a moderate-temperature, preheated oven.

However, glass containers in your kitchen, like drinking glasses and glass bowls, are typically not made for oven use. So you should keep them out of high heat unless they are labeled as oven safe.

Put glass in the oven if it’s oven-safe glass.

Can you put glass in the oven

Can you put glass in the oven at 350?

In general, stoneware, tempered glass (such as pyrex or corning ware), metal, enamelware, and ceramic should be oven-safe up to at least 350°F.

Hand-blown glass should not go in the oven.

Can you put glass in the oven at 450?

Testers put dry sand in the bakeware, which gets hotter than food. Then they put the glass dishes in an oven for 80 minutes at 450 degrees. And they are still fine.

Just remember to avoid thermal shock. It also depends on types of glass.

The best way is to put an oven-safe glass in a preheat oven and never excess 425°F.

Can you put Pyrex glass in the oven?

Can you put Pyrex glass in the oven

You can put Pyrex glass in the oven. Pyrex is safe in a preheated oven.

Pyrex cookware is durable, attractive, and comes in a wide variety of shapes and sizes. But there are concerns about using Pyrex glass in the oven.

It’s important to know how to use Pyrex products safely and properly. Remember that Pyrex cookware is over-safe with the glassware, while the plastic lids are not.

Be cautious to avoid thermal shock. If you’re using Pyrex cookware in the oven, keep these tips in mind:

  • Always preheat your oven before inserting Pyrex glassware.
  • Never exceed 425°F.
  • Make sure the glassware is at room temperature before exposing it to heat.
  • Add a small amount of water to the bottom of the glassware before placing it in the oven.
  • When removing Pyrex bakeware from the oven, pay attention to where you place it.
  • Use both hands to move it.
  • Make sure to set the cookware on a dry cloth surface such as a folded towel or potholder.
  • Never expose hot glassware to cool water or a cold surface.
  • Don’t take it straight from the fridge to the oven.

Can you put cold glass in the oven?

Glass cookware doesn’t handle temperature changes well. They can break or shatter if the temperature suddenly changes.

Never go straight from the fridge or freezer to the oven. You’re running the risk of the glass breaking while doing this.

When putting glass in your oven, it’s best to go from room temperature to a preheated oven.

How to know if glass is oven safe?

To ensure safety while cooking, here are some tips to know if your glass cookware is oven-safe:

Check the label

There should be a label on the bottom of your glassware that indicated the glass is safe for use in the oven.

However, your glassware is oven-safe doesn’t mean it can be used for any temperature your oven is capable of.

You may also see a symbol with wavy lines and a temperature, which means it can be used in the oven as long as the temperature doesn’t go higher than the number.

You can find information on their site about the maximum temperature that the glass can be used in if there is no label found on the glassware.

Check if it is Pyrex glass

How to know if glass is oven safe

Pyrex glass is a line of clear and low-thermal-expansion glass products for laboratories and kitchens.

The shock from sudden thermal expansion of glass causes it to break or shatter. One can safely place glass in the oven if it is Pyrex glass.

Pyrex glass can withstand heat reaching 350 to 450°F (177 to 230°C), making it safe to use in baking where moderate to hot temperatures are required.

Check if it is Borosilicate glass

Borosilicate glass will not crack, break, or shatter when subjected to extreme temperature changes.

Anchor Hocking, OXO, and CorningWare are notable brands of borosilicate glass cookware and bakeware.

Borosilicate glass can handle higher temperature ranges compared to Pyrex glass. It can handle oven temperatures of 350 to 450°F (177 to 230°C) and can tolerate up to 752°F (400°C) for a few minutes.

You can immediately wash your borosilicate glassware after cooking or baking, or cook or reheat frozen food in the oven without worrying that the glass will crack or break.

Check if it is a tempered glass cookware

How to know if glass is oven safe

Another type of glass you can rely on for safe oven use is tempered glass.

Tempered soda-lime glass is the most common type of tempered glass used for cookware and bakeware.

Tempered glass has high thermal shock resistance and low coefficient of thermal expansion.

Another advantage of tempered glass cookware is that it’s able to withstand breakage from being dropped.

Aside from that, it will break into small, rounded chunks instead of sharp, jagged pieces, reducing the risk of injury, and making its disposal safer.

Make sure there are no metallic components

If your glassware has metallic components, it is more susceptible to cracking or breaking due to the differences in thermal expansion of glass and metal.

The cooldown rates of glass and metal differ as well, with the former having a slow cooldown and the latter having a fast cooldown.

It is another factor that can contribute to breaking due to thermal shock.

How to keep glass from breaking in the oven?

After knowing can you put glass in the oven, let’s see how to keep glass from breaking in the oven.

How to keep glass from breaking in the oven

To safely heat your food in glass, here are some tips to know:

Don’t change temperatures drastically

Glass cookware doesn’t handle temperature changes well. When putting glass in your oven, it’s best to go from room temperature to a preheated oven.

Never go straight from the fridge or freezer to the oven.

Do the same when taking your glass dish out of the oven. Don’t put it on a cold surface.

Place it on a warm or room-temperature surface instead, such as hot pat.

Use the correct glass

Only use glass that has been treated and is durable enough to withstand the hot temperatures of an oven. The correct glass types, such as tempered or borosilicate glass, will be less likely to experience a thermal break.

Avoid high temperatures

When using oven-safe glass, make sure to adhere to the upper temperature limit recommended by the manufacturer.

This temperature limit could be anywhere from 350°F to 500°F, but try to stay below it to be on the safe side.

Look for structural weaknesses

Inspect the glass to make sure it is free of any small cracks or scratches.

Also, make sure there are no metallic components on the glass.

Add liquids to the bottom for dry foods

When baking dry foods in a glass pan, add a small amount of water to the bottom of the pan.

When the dry food cooks, it will likely release some water content, which will find its way to the surface of the glass.

Since this water might still be cool, you may not want it contacting the hot surface of the glass.

Add a thin layer of water to the bottom layer of the glass to allow the water to warm up as the glass is heated.

Car FAQs

Can glass explode in the oven?

Glass can explode in the oven. All glass, even borosilicate, can experience thermal breakage if exposed to sudden or uneven temperature changes.

At what temperature does glass break in the oven?

When heated, thin glass begins to crack and typically breaks at 302–392°F. High heat (>300°F) and excessive thermal variations can cause glass bottles and jars to shatter or break.
Borosilicate, Pyrex and tempered glass has higher heat endurance, 350 to 450°F (177 to 230°C) and can tolerate up to 752°F (400°C).
