To prevent thermal shock, which might cause the glass to break, you should make sure the glass is safe to use at high temperatures before you pour hot coffee into it.

When the coffee is hot but the glass is cold, thermal shock happens, and the glass breaks.

Some glass stemware is thin and more prone to fracture when exposed to high temperatures.

For use with hot coffee, there are certain glasses that are heat- and temperature-resistant, but you must first confirm this.

How do I know if I can put hot coffee in a glass?

High temperatures may or may not be able to break the glasses. It will be safe to use in temperatures between -5oC and 65oC / 20°F and 150°F. Any temperature over that will put a conventional glass tumbler at risk of breaking.

High shatter, a stronger and more durable material, is used to make heat-resistant cups. In order to avoid breaking or cracking, you can use them for hot coffee or other hot beverages.

Thermal shock occurs when the glass is cold or at room temperature and then exposed to high heat from the liquid. This causes the glass to expand very quickly and then break.

There are a few things to do when you pour hot water into a glass to ensure it doesn’t crack. Here are a few ways to avoid heat shock.

Don’t pour fast

Rather than pouring the hot coffee into the glass too soon, do so gently. This avoids heat shock and helps the jar to slowly adjust to the high temperature.

Pour a small amount of hot coffee into the glass, wait a few seconds, then slowly pour the rest.

before use, warm the glass

Thermal shock occurs when glass is at a lower temperature than hot water. so when hot water is poured on glass, the rapid change in temperature can cause cracks.

Before adding the hot water, you can warm the glass to avoid this.

The best method is to clean it with a little tap water, fill it about halfway, and then add some hot water. This will warm the glass and get it ready for the hot drink.

Place a metal spoon in the glass

The addition of such a metal spoon to the glass is one smart method you may apply to prevent heat shock. Because metal is an excellent conductor of heat, it will absorb part of the heat from the hot water and reduce the risk of thermal shock.

Pour the hot coffee over the metal spoon before putting it in the glass so the heat is absorbed before it gets to the glass.

Yes and no. You can put a glass in the freezer since it doesn’t have a high freezing point, so it can’t actually be frozen, but we don’t recommend leaving the glass in the freezer for too long.

However, you can leave a drinking glass in the freezer for a short time to freeze before using it for a cocktail or cold drink.

Why did my glass cup break when I pour hot tea over it?

A glass’s inside surface quickly warms up when hot liquid is poured inside of it. The exterior surface is therefore under stress. Glass does not respond well to stress, therefore if the exterior surface has any minor flaws (such as places where glasses rub against one another on the shelf), a crack might start there.
