“Okay, we’ve all been there. You’re in a hurry, you need to make some food or heat something up, so you toss it in the microwave. But then you realize, oh no! I forgot to take the ice out of my drink! Will it melt? What will happen?”

We’ve all had that moment of panic when we realize we’ve left something important out of the equation. In this case, it’s ice in your drink and whether or not Microwaving your beverage with ice still inside is going to ruin everything. So, does ice melt in the microwave? We did some research to find out once and for all. Here’s what we found.”

Does ice melt in the microwave

Does Ice Melt In The Microwave?

Ice does melt in the microwave, but not as fast as you assume. At least, not faster than it generally melts at room temperature without any external heat. 

The answer is negative because of the function of the microwave. The working procedure of microwaves doesn’t favor melting ice. But why does this happen?

We know that the microwave heats foods kept inside it. But unlike a stove, it doesn’t generate heat to warm up the food. Instead, it uses a microwave that goes through the food and warms it up. 

In the case of water, the microwave heats it by rotating the molecule. But ice is in solid-state; the microwave can’t rotate it, making it hard to melt.

On the other hand, ice water is a hydrogen-oxygen solid bond. That’s why it takes a lot of energy to break, which the microwave doesn’t contain. There is also another reason, ice doesn’t heat like water because water can absorb microwaves, but solid ice can’t.

However, if it’s not rock-solid ice and normal frozen food (like cake or some other soft food), then the microwave might be able to warm it up like any other food. 

So, overall, a slight frost of ice might get melted quickly in the microwave, but an ice cube would take a reasonable amount of time.

Here is a video from “Impossible Science” youtube channel about “Ice That Refuses To Melt In A Microwave”

What Happens If You Put An Ice Cube In The Microwave?

Ice means a locked position of water, and our microwave can not produce the amount of heat required to change the condition of ice to water. We can see that the ice on the frozen food has started to melt at room temperature. 

When warming up the water, the microwave rotates the molecule of water in order to heat it. But in the case of ice, the molecules are in a solid and locked position, making it harder for the microwave to rotate them. So the microwave can not get through it, and thus, fails to melt it.

Why Are People Putting Ice Cubes In The Microwave?

There are various reasons one might put ice cubes in the microwave. This could include collecting water from ice, melting frozen raw or cooked food quickly, melting some ice or other frozen food, making dessert from ice cream, and many others. 

Moreover, Putting an ice cube on your food and putting it in the microwave causes steam that reheats your food. The steam will diffuse to go through all over the food, and for this reason, you could find your food warm. Not a part will remain cold.

How Long Does It Take To Melt Ice In A Microwave?

It actually depends on the size and the condition of the ice you are putting into it. A small frost of ice may melt almost instantly. But if it’s an ice cube of standard size, it may take up to 3-5 minutes to melt, which is nearly similar to what it would take at room temperature.

Moreover, if it is a solid ice block, it would take more time to melt. On the other hand, it might help you melt the block more quickly if it is already leaking.

However, there are ways to melt ice quickly in a microwave as well. Let’s find out how.

How Do You Melt Ice Quickly?

The most straightforward method is to add some water along with the ice in your microwave. Now turn on the microwave and wait for the result. It will melt the ice faster than only the ice being there does.

Why does it happen? The answer is simple. The microwave heats up the water. So the warm water melts the ice easily.

Is Microwave More Efficient At Boiling Water Or Melting Ice?

When it is only about boiling water, a microwave is not very efficient. A stove is always better to boil water as it can use more power to heat the water. 

On the other hand, an electric oven converts the electrical energy to the microwave, then heats up. It also can’t use much power as that might risk blowing the circuit breaker.

However, if you compare the efficiency with melting ice, boiling water in the microwave is way more efficient. Because, in the case of boiling water, it works enough to get the job done. While in the case of melting ice, it does almost nothing.

Is It Safe To Microwave Ice?

We have already seen that using a microwave to melt ice is not very fruitful. Still, if there is some reason you want to try it, you may need to consider some conditions first.

Putting ice in a microwave might not cause any significant issues. Yet, as the microwave does not affect the ice, there is a possibility that it might act as an empty microwave which could break the microwave. 

So, it is safer not to block ice or ice cubes in a microwave. 

Is It Safe To Microwave Ice Cream?

Ice cream is not the same as a cube of block ice, so it should not be much of an issue to heat ice cream using the microwave. It will act just like any other cold food.

However, you should be aware of the ingredients the ice cream contains. For example, heating a natural raw egg ice cream using a microwave might not be healthy for you and cause problems.

Is It Ok To Microwave Iced Coffee?

Yes, it is entirely ok to microwave iced coffee. Iced coffee contains almost the same ingredients as regular coffee. However, microwaving iced coffee might not give you the same taste.

Moreover, you must be careful as to the cup of the container you are using to warm your iced coffee. Check if it is microwaveable and only proceed if the answer is positive.

Is It Ok To Put Ice In Rice To Microwave?

It is a regular practice to put ice when warming rice in the microwave in some households. It actually relates more to the water of the ice than the ice itself. 

You might already know that boiled rice is cooked by boiling them with water. If you put an ice cube with your rice in the microwave, it can’t melt, but it will produce steam which will take some time to reheat the rice and be edible for you. 

So, there is no problem putting ice in rice in the microwave.


Microwaves are useful for many reasons, but sadly, melting ice is not one of them. But that should not prevent you from utilizing your microwave in other cases. Though ice doesn’t melt in the microwave, you can use the microwave oven to warm up other soft or cold foods. 

In the case of ice, it’s better to use a stove or average room temperature to melt it.
