Can I pour boiling water into Pyrex?

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.

Is Pyrex safe for boiling water?

Can you put boiling water in Pyrex? No. Provided you heat Pyrex at a reasonable rate it can withstand temperatures much higher than boiling water. However if you thermally shock Pyrex it may break (by taking a Pyrex Bowl out of the freezer and plunging it into boiling water for instance).

Can you pour boiling water into a Pyrex measuring cup?

A Pyrex measuring cup can handle a temperature difference of about 100 degrees. … Boiling water into the cup, decant it and within about 30 seconds you will be able to handle the cup without it burning you.

Will Pyrex crack from boiling water?

It is stronger than borosilicate glass, but when it’s heated, it still expands as much as ordinary glass does. It doesn’t shatter immediately, because the expansion first acts only to release some of the built-in stress.

Can you pour boiling water into glass?

Pouring boiling water into a glass is highly likely to shatter it, because the hot water contacts part of the glass first, whereas other parts of the glass (such as the outside of the cup) remain cooler. When you pour hot water into a glass (which is at room temperature), the inner layer of the glass will absorb heat.

Can I put hot stuff in pyrex?

Pyrex® Glass Use & Care

Avoid sudden temperature changes to glassware. DO NOT add liquid to hot glassware; place hot glassware on a wet or cool surface, directly on countertop or metal surface, or in sink; or handle hot glassware with wet cloth.

How hot does Pyrex need to be to crack?

Just running the numbers on the physics of the glass, they found that the temperature change needed to break borosilicate glass is more than 300 degrees F, while soda lime silicate glass will shatter after a change of just 99 degrees F.

Can you put Pyrex in a steamer?

A pyrex pie dish, or other dishes safe for oven use, will work well. … Note that there must be enough space between the outer edges of the dish and the sides of the pot so the steam can come up and cook the food.
