Why does a Pyrex glass not crack when boiling hot tea is poured into it?
Answer. Explanation: The reason is that as the glass heats, its density changes; it expands. 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.
Does boiling glass weaken it?
Putting boiling water on a frozen windshield will not cause the windshield to shatter.

Why does glass break when heated?
The glass breaks on heating due to thermal shock. Whenever there is difference in temperature between two surfaces of the glass, the thermal expansion of one side with respect to other side induces stress in the material. When this stress reaches above the yield strength of the material the cracks start to develop.
