Can You Boil Water In A Glass Bowl On A Stove?

Whether or not water can boil in a glass bowl depends only on the quality of the glass. If you use cheap glass bowls that have impurities, they may break as soon as you put them on the stove. So it is forbidden to use these glass bowls on the stove for boiling.

But the results can be different if you use high-quality glass bowls like Pyrex. You can safely boil the water in Pyrex bowls on the stove.

After reading this article, you get to know why boiling water in a glass bowl on the stove is not safe. And what conditions are necessary for boiling water in a glass bowl safely?

Can A Glass Bowl Break On the Stove?

Cheap glass bowls with impurities or cracks can easily break on the stove whether it is electric or gas. Before boiling the water in the glass bowl, check the material of the bowl to see if it is stove-proof or not.   

High-quality glass bowls can also break while boiling on the stove if they have cracks. Or you are directly boiling the bowls on the stove.

Direct heating of the glass bowls can also cause cracking and shattering because uneven heating of the stove can cause thermal shock to the bowl. When we directly boil the water in the glass bowl, there is a high chance of uneven heating. 

It is possible that one side of the bowl gets more heat than the other side. This uneven heating causes thermal shock to the bowl. The bowl can break into pieces due to this thermal shock.

Safest Temperature For Boiling In A Glass Bowl:

If you are using a high-quality glass bowl for boiling water on the stove, then temperature is not the issue. Care Should only be taken that the temperature does not exceed its melting point.

You should know the safest temperature of glass bowls before their use on the stove. The main issue is not the high temperature, the real issue is sudden temperature changes. 

When you heat the glass unevenly or put the cold bowl at high temperatures, these can cause thermal stress.

Some glass bowls can bear high temperatures without any side effects like Pyrex (borosilicate). 

Borosilicate can tolerate temperatures up to 400°C for a short time, normally they can tolerate 200-230°C.

Role Of Heat Diffuser On The Stove:

Heat diffusers play a very crucial role on the stove for the safe boiling of water on the stove.

The glass bowl doesn’t crack every time it is placed on the stove. Sometimes you can safely use the glass bowl on the stove luckily.

But the chances of glass breaking on the stove are so high that it is not considered right to use it on a stove directly.

Direct heat from the stove can cause thermal shock to the glass bowl. That’s why it is recommended to use a heat diffuser on the stove during the boiling of water.

You can use a wire grid to separate the glass bowl and the stove during boiling. The wire grid ensures the even heating of the glass bowl. Gradual heating saves the glass bowl from thermal shock.

Which Stove Boils The Water Faster?

The induction stove boils the water 25-50% faster than a gas or normal electric stove. It uses the electromagnetic field around the copper wire to generate heat. It’s easy to use. 

But it is not best for glass bowls because glass is not a good conductor as metals. It takes more time to heat up and proper attention for safely boiling.

Stainless steel, copper, and cast iron are the best materials for use on the induction stove.

You also need a heat diffuser to boil water in a glass bowl on an induction stove.

Best Glass For Boiling On The Stove:

Borosilicate glass is known for its non-porous, unreactive, heat and chemical-resistive properties. Additionally, it never absorbs the flavor and color of food.

Borosilicate has a lower coefficient of thermal expansion (5 × 10−6/ °C at 20 °C), so it can bear the high temperature without expanding.

That’s why it is considered the best glass for boiling water on the stove. Not only for boiling but also for other types of cooking.

Pyrex is the brand name of borosilicate. It is the ideal glass for use on the stove because it is heatproof.

But it is forbidden to heat the glass bowl directly on the stove, no matter how good the quality. If you want to avoid any unwanted situation during the boiling of water in the glass bowl, then using a heat diffuser is recommended.

Tips For Safe Boiling Of A Glass Bowl:

You can use the glass bowl for boiling water or other types of cooking but with safety precautions.

Check The Material:

Always check the quality of the glass bowl before putting it on the stove. Whether it is flameproof or not. Impurities or cracks in a glass bowl can cause it to break.

Avoid Thermal Stress:

The most important reason for breaking a glass bowl is thermal stress. Sudden thermal changes can easily break the glass bowl.

When we put the cold glass bowl in the hot stove, sudden temperature changes occur. Which becomes the reason for the breaking of a glass bowl.

Gradual Heating:

Try to heat the glass bowl gradually while boiling. Gradual heating decreases the chances of the shattering of glass.

Avoid Direct Heating:

You can use the glass bowl for boiling but can’t heat the bowl directly. Direct boiling can cause uneven heating which eventually causes thermal shock. So it is advisable to use a heat diffuser between the stove and the glass bowl.

Summary: 

Now, you can take all the information related to glass bowls and stoves after reading this article. Cheap glass material can cause unwanted situations due to its cracks or impurities.

You should use high-quality glasses that can bear high temperatures like borosilicate or Pyrex. 

High temperature itself has no side effects on the glass bowl. Glass bowls crack due to thermal shock. Sudden temperature changes can break the glass bowl due to thermal shock.

You can safely boil the water in a glass bowl by using precautions including a heat diffuser.

FAQs:

Can a glass bowl break from hot water?

Glass bowls break due to sudden thermal changes. When you put hot water in a cold glass bowl, it can easily break. Because these sudden thermal changes cause thermal shock to the bowl. Consequently, the glass bowl breaks.

Why is Pyrex oven-safe?

Normally, Pyrex isn’t affected by the temperature. Sudden temperature changes or thermal stress can have a bad effect on the glass bowl.

The oven evenly heats the utensils, so there is no chance of thermal shock. This is the reason you can easily use Pyrex in the oven.

Why is a heat diffuser necessary between a glass bowl and the stove for boiling water?

Uneven heating can occur as a result of directly heating the glass bowl on the stove. Consequently, a glass bowl can break. This is the reason heat diffusers are used to avoid direct heating.

Heat diffusers play an important role in the safe boiling of water in a glass bowl. It ensures equal heating of the glass bowl during the boiling of water.

Can we use a Pyrex bowl on an electric stove?

Pyrex glass is heat-resistant, chemical-resistant, and unreactive material. Due to its low thermal coefficient, it can tolerate high temperatures without expanding.

That’s why you can use Pyrex glass on an electric stove. But we can’t directly heat the Pyrex bowl on an electric stove due to thermal shock.

Will a glass dish be broken by boiling hot water?

When boiling water is poured into a glass, it is very likely to break because the hot water only reaches a small portion of the glass at a time while the rest of the glass, like the outside of the cup, remains cooler.
