Pyrex uses borosilicate glass to make kitchenware that can be used in a microwave, oven and even on the stovetop. Home kitchen appliances, including the microwave, are not able to reach that level of heat. So, there is no need to worry about melting when you microwave Pyrex.
Can you heat Pyrex in the microwave?
Pyrex® Glassware can be used for cooking, baking, warming and reheating food in microwave ovens and preheated conventional or convection ovens. Pyrex Glassware is dishwasher safe and may be washed by hand using non-abrasive cleansers and plastic or nylon cleaning pads if scouring is necessary.
Does glass heat up in the microwave?
Natural glass is quite common and for the most part happens to be safe for cooking in a microwave oven. You can put thick natural glass container in a microwave and it will not crack, break or melt. As the glass container heats up, the movement of the molecules becomes faster. Glass is a good conductor of heat.
Why did my Pyrex dish exploded 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.
What is the temperature limit for Pyrex?
The maximum recommended working temperature for PYREX laboratory glassware is approx 500°C (for short periods of time only). PYREX glass also performs well at lower temperatures. This glass can withstand conditions down to -190°C and is suitable for use with liquid nitrogen.
Can you microwave a glass jar?
Yes, newer jars have a microwave-safe symbol on them. It is important to keep in mind that glass mason jars are non-reactive but still become very hot to the touch. For this reason, it’s best not to package anything that requires long periods of microwave heating in mason jars.
What is not microwave safe?
Materials Unsafe in the Microwave Cold storage containers (such as margarine tubs, cottage cheese, yogurt cartons). These materials are not approved for cooking, and chemicals can migrate into food. Brown paper bags, newspapers, and recycled or printed paper towels.
Why does glass get hot in microwave?
Metal tends to reflect microwaves, which is why they are used to shield the oven to prevent it from leaking. “Microwave-safe” materials, like glass, paper, and most plastics, allow microwaves to pass through them. In the case of ceramics, they may contain materials that increase the absorption of microwaves.
How do you stop Pyrex from exploding?
It’s best to put the dish on a dry dish towel or a metal cooling rack to cool. Damp towels or surfaces can also cause the hot glass to shatter. Don’t use tempered-glass bakeware on the stovetop, under the broiler, in a toaster oven, or on a grill.

Can Pyrex withstand 500 degrees?
A: Pyrex is suitable for use from -192°C to +500°C. This makes it an ideal choice for lab glassware which will be directly heated. Remember that heating and cooling should always be slow and steady – Pyrex can withstand huge temperature changes, but if they are too sudden it may still crack due to thermal shock.
Can I bake in Pyrex at 450?
Pyrex is meant to be able to withstand higher temperatures. 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.
Can Pyrex handle boiling water?
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 can you tell if a glass is microwave safe?
