Why does glass break when boiling tea is poured in it very fast?

There are a few reasons why glass breaks when boiling tea is poured in it very fast.

Thermal shock

When boiling tea is poured into a glass, the sudden temperature change causes the glass to expand rapidly. This expansion can cause the glass to crack or shatter. The greater the temperature difference, the more likely the glass is to break.

Mechanical stress

The boiling tea can also cause mechanical stress on the glass. The weight of the tea and the force of the water hitting the glass can cause it to break.

Chemical reaction

The boiling tea can also react with the chemicals in the glass. This reaction can weaken the glass and make it more likely to break.

Other factors

There are a few other factors that can contribute to glass breaking when boiling tea is poured into it. These include:

* The type of glass. Some types of glass are more resistant to thermal shock than others.

* The thickness of the glass. Thicker glass is less likely to break than thinner glass.

* The shape of the glass. Glasses with sharp corners or edges are more likely to break than glasses with smooth curves.

How to prevent glass from breaking when boiling tea is poured in it

There are a few things you can do to prevent glass from breaking when boiling tea is poured in it. These include:

* Use a glass that is made of heat-resistant glass.

* Preheat the glass before pouring boiling tea into it.

* Pour the boiling tea slowly into the glass.

* Do not pour boiling tea into a glass that is already hot.

* Avoid using glasses with sharp corners or edges.

By following these tips, you can help to prevent glass from breaking when boiling tea is poured into it.
