Why is the colour of ice from refrigerator white and the colour of ice from glacier blue?


Whenever we hear the word ice, the first image that comes to our mind is of the white ice frozen in the freezer. Because of this, we think that the color of ice is white. But, when we talk about glaciers, the color of this ice becomes blue. Let us now know why the color of glacier ice is blue and why the color of ice in the refrigerator is white.

Why is the color of ice white?

When we keep water in the refrigerator, it turns into white ice after freezing. Talking about the science behind this, this happens because when water turns into ice, the air present in it also freezes. When the waves of light fall on it, the color of the ice in the refrigerator appears white to us. This happens due to the reflection of light.

Why is the colour of glacier ice blue?

Now the question arises that when the process of freezing of ice is the same, then why is the colour of glacier ice blue and the colour of fridge ice white. You have come to know about the colour of fridge ice. Now let us tell you about glacier ice. According to the report of Alaska Education’s website, the colour of glacier ice is blue because that ice does not contain only water and air.

Many times many types of chemical elements are present in it. Along with this, the molecules of glacier ice are so glued together that there is almost no scope for air in it and due to this reason when light falls on it, the glacier ice appears blue or sky blue to us. However, this happens only with the ice frozen inside the sea.
