Are Pyrex Containers Safe For Use In The Oven? Here’s What Experts Think

Pyrex is a brand name for a unique type of heat-safe glass called borosilicate glass, developed by Corning Glassware Company. That name was coined from the glass's component, and it remains in use even long after Corning stopped using borosilicate glass in favor of the cheaper soda-lime glass.

If you're wondering whether this glass is oven safe, then you'd be glad to know that "yes, it is!"

All forms of Pyrex bakeware are safe to use at high temp conditions like in your oven and microwave, as long as you avoid sharp or sudden temperature changes. Here's Why:

The modern Pyrex is made of soda-lime glass, which tolerates both hot and cold temperatures well. However, the former placeholder, the borosilicate glass, is much more resistant to thermal shock. This means that exposing the modern Pyrex to sudden temperature changes compromises the integrity of its structure and can be very dangerous — it could crack, shatter, or worst-case scenario, explode!

There are, however, a few more delicate details to keep in mind when it comes to thesis omg your Pyrex safely. So, keep these few points in mind:

1. Pay Utmost Attention To Liquids Around Heated Pyrex

If you’re using Pyrex to cook something that may release liquid, add a small amount of liquid to cover its bottom. This helps you minimize effects of any change in temperature from the liquid that may get released from the food during cooking.

Also, make sure that your oven gloves or potholders are completely dry before using them to transfer the Pyrex. Even a liquid at room temperature liquid can cause them to shatter!

2. Let The Pyrex Cool Down To Room Temperature

Before stacking your Pyrex containing leftover or reheated meals in a fridge or freezer, make sure they have totally cooled down to room temperature first.

3. Always Preheat Your Oven Before Use

Experts advise preheating your oven before placing Pyrex glassware in it. This is backed by usage instructions on the Pyrex website, which says that direct heat during preheating can lead to breakage.

4. Place It On A Wooden Board Or Cloth

After removing your Pyrex from the oven, transfer it to a "safe" surface. The surfaces that classify as safe include a kitchen towel, a dry cloth potholder, a wooden trivet, or a cooling rack. Never put hot Pyrex directly on the counter, or a wet, metal, or cool surface.

5. Never Place Your Pyrex On A Stovetop

Pyrex glassware is only certified safe for use in an oven and microwave, so it should not be used for other types of cooking or on a direct heat source. That is why the surface of your gas or electric stovetop, under a broiler or in a toaster oven, dangerous "surfaces" to place your Pyrex on.

In conclusion, the key point is that yes, Pyrex glassware is oven safe. However, you must pay extra attention when using them, and sudden exposure to temperature changes may result in a home accident.
