Can You Broil Pyrex

Can You Broil Pyrex?

It is well known that Pyrex makes durable cookware that can be used in multiple ways. But can it handle broiling temperatures?

Even though Pyrex produces high-quality and durable glassware, it shouldn’t be used for broiling because the unusually high temperatures can shatter the glass.

Find out what Pyrex bakeware is suitable for, how strong it is, and what equipment you should use for broiling with Pyrex bakeware!

How Tough Is Pyrex?

With good reason, Pyrex has been around for decades.

As one of the leading names in high-quality glassware, it has cemented its reputation by producing some of the industry’s toughest and most advanced products.

However, glass has fundamental flaws and can’t defy the laws of thermal dynamics.

Although you can toughen glass to withstand high temperatures, glass will always be less durable than other materials in the kitchen, especially at high temperatures.

In addition to using borosilicate glass to reduce thermal expansion and stress, Pyrex’s glassware is made with advanced manufacturing processes to further enhance its quality.

Customers can cook and heat food in the dish without worrying about damage – unless, of course, they go above a certain temperature range, like when broiling.

Why Does Glass Shatter?

As glass is heated, it can expand by tiny amounts in different areas – this expansion causes tiny fractures in the glass that eventually lead to its combustion.

Glass can combust quite violently if not treated properly.

The danger of this flaw is that it can result in glassware shattering as soon as you remove it from the oven and set it on the counter.

Mechanical stress, i.e., picking up and setting down glassware, causes this phenomenon

Even though putting it up and down isn’t much, it’s enough to completely shatter the glass.

But it isn’t all bad!

Generally, Pyrex products work well at certain temperatures.

Pyrex containers can easily be heated up to 400°F–425°F when used exclusively for heating food.

In most cases, this is the maximum limit set by the brand for its products, but check your specific glassware product’s user manual or handling instructions to be sure.

Because Pyrex works well at freezing temperatures, it is also one of the best ways to conveniently heat food right from the fridge or freezer.

Pyrex products can be frozen rock solid at 0°F and placed directly in the oven at up to 400°F without shattering.

As Pyrex seems to be able to handle varying temperatures, things are quite different when broiling.

What Is Broiling?

In order to cook food and give it an interesting texture, broiling relies on high heat.

During broiling, food is exposed to higher temperatures than usual, usually 400°F to 550°F.

In order to give the superficial layer some color and crispness, broiling is primarily used at the end of the cooking process.

Broiling, however, can be quite dangerous when glass is involved.

If most glass products have an upper temperature limit, broiling comfortably crosses it and easily reaches uncomfortable levels.

When this type of heat is applied to glass, it will shatter – no matter what type of glass you use! Some ovens have a dedicated broil feature that can raise the internal temperature to 500°F!

Why Shouldn’t You Use Pyrex For Broiling?

You might think that you can broil food at or below 400°F when Pyrex can handle temperatures up to 400°F.

Usually, ovens aren’t that accurate when it comes to temperature – and ambient conditions can cause a slight discrepancy in the oven’s internal temperature.

The type of food you heat in the glassware can also significantly affect the temperature of the glass.

When thick foods like lasagna cover most of the glassware, they will heat up very quickly and may even cause the glass to break.

Consider yourself lucky if you’ve previously used Pyrex at such high temperatures and the glassware survived – because you probably won’t be able to repeat your feat!

Glass will likely develop faults around its surface when heated past its recommended temperature zone.

Under a microscope, these faults will not be visible to the naked eye, but they can be detected under a magnifying glass.

As a result of these microfractures, the glass structure becomes unstable, and will likely shatter when exposed to the same high temperatures again.

Best Materials For Broiling

To conclude, Pyrex shouldn’t be used when broiling food. Instead, we recommend the following alternatives to achieve the best results.

1. Steel 

In general, steel is a strong, durable material that can hold its shape under mechanical and thermal stress. It has been used to cook food under direct heat for centuries.

Steel is much more temperature-tolerant than most oven materials and can easily withstand their maximum temperatures.

Unlike other materials, steel products are excellent at spreading heat evenly around the pan, resulting in better and more uniform superficial textures.

You can broil food with cast iron, steel, stainless steel, or virtually any other steel bakeware that is food/oven safe.

Despite looking cool when it comes out of the broiler, steel is notorious for blistering fingers instantly!

2. Aluminum

Another great material is aluminum, which is lightweight and easy to handle.

Usually, you should use oven-safe aluminum bakeware for broiling food due to its cost-effectiveness and ease of use.

In comparison to steel pans, these heat-resistant bakeware products are available in multiple sizes and provide similar results.

3. Porcelain

Although porcelain products are more expensive, they are one of the best bakeware for broiling.

Material made from refined ceramic is specially treated with higher temperatures, resulting in a stronger structure and greater tolerance.

As opposed to steel or aluminum, you can use them straight from the fridge or freezer without worrying about damage! Sure, they might break when dropped, but they heat food more efficiently than steel or aluminum.

4. Ceramic

For people who want the same characteristics as glassware, ceramic bakeware is a good option.

In general, these pans are well-suited to broiling temperatures, even though they are less durable than porcelain.

They come in many different sizes and can be printed with designs too – which makes ceramic bakeware great for everyday use in the kitchen. Ceramic bakeware is also cheaper.

Safety With Pyrex

Pyrex can be used in several ways. Here are a few tips to keep in mind:

  • You should always follow the instructions on the packaging and the instructions on the user manual of your glassware. If you don’t have the original packaging, check out the details on the manufacturer’s website.

  • Heat food a few degrees lower than the maximum recommended temperature for your glassware. Remember: ovens are inaccurate and temperatures can vary slightly.

  • Use thick gloves when handling hot glassware. Keep the dish away from your body when moving it.

  • Afterward, place the Pyrex on a dry counter after cooling down for a few minutes in the oven – this will allow the material to regain its structural integrity.

Related Questions 

Here are some questions in relation to broiling food in Pyrex now that you know why you shouldn’t do it!

Can you use old Pyrex in the oven?

You can use the Pyrex in the oven for everyday kitchen tasks as long as it is in good condition.

Because it has been repeated used in the past, old Pyrex glassware is likely to crack or shatter when broiling food.

Can you broil Pyrex for a few minutes/seconds?

Pyrex shouldn’t be broiled for a short period of time either since it will likely reach its maximum temperature after a few minutes in the oven.

Furthermore, after broiling for that short a time, you probably won’t get the desired food benefits.
