Are glass measuring cups heat safe?
The very nice thing about a Pyrex measuring cup is that the glass is tempered and can handle hot liquids. Heat up water for cocoa, or tea, or heat stock for risotto in the microwave. What the heck, heat your milk for making a white sauce, reheat gravy or melt butter for popcorn or lobster.
Why did my Pyrex measuring cup explode?
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.
Can you pour boiling water into a Pyrex measuring cup?
The effect of thermal shock is powerful and results in the cracking of glass. 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.
