Most people are unsure about the nature of the ice. People are confused if it is alloy, mineral, rock, or metal. We will provide a detailed answer to that confusing question is ice a mineral?
Yes, ice is a mineral because the mineral has four characteristics. It is available in a solid-state. You can find it in nature easily. It has a definitive chemical composition as it is made with repeating crystalline structures.
Is Ice a Mineral?
Ice is a mineral because it fits the definition of a mineral. Ice in glaciers is also a mineral. We will look into the details of the mineral definition to confirm the mineral status of this substance. According to the International Mineralogical Association, a mineral is a substance that meets the underlying criteria:
- It is a naturally occurring substance formed by natural geological processes.
- It is a solid substance in its natural occurrence.
- It has a well-defined crystallographic structure.
- It has a well-defined chemical composition.

A substance can be a mineral if naturally available without human or animal intervention. Ice meets all of these requirements. Liquids and gases cannot be minerals because the minerals only occur in the solid-state.
When you look at the mineral in the microscope, you will find a perfect crystalline structure. It is also crucial that mineral has a specific chemical composition.
You cannot classify a substance in the class of minerals if you are unsure about the chemical composition.
We will test the ice on each of the parameters of the mineral definition. Ice is solid because it retains its shape. You cannot classify the water vapors as minerals.
Ice form different crystalline structures when you cool it at different rates. The most common is the hexagonal arrangement of the oxygen and hydrogen atoms. Oxygen and hydrogen atoms create water molecules.
When they are in ice form, they will bind themselves with weak bonds. Ice covers almost 9 percent of the earth’s surface. It is really interesting to know that the smallest snowflake to the largest glacier are both minerals.
It indicates that it is widely available in nature without the intervention of humans. Finally, everyone knows about its chemical composition.
You can make it with two hydrogen atoms and one oxygen atom. When we look at all the information, it is easy to classify the ice in the mineral category.
Here is the official IMA List of all minerals to prove that ice is a mineral. It includes ice and thousands of other officially recognized minerals globally.

Is Water a Mineraloid?
Some people argue that water should be considered a mineraloid. A mineraloid is a substance that does not meet all the requirements to classify as a mineral. If a matter does not have an amorphous structure and meets all the other needs, you can add it to the mineraloid category.
Some people think it is not solid as you can easily break it as it bends when you apply force. It is not true as ice is solid. It retains its shape at temperatures below zero.
It does not have any issues with the other parameters of classifying a substance in the mineral class. If you look at the website of mineralogical associations, you will find ice in the list of minerals.
As international organization accepts ice in the list of minerals and it does not have issues in any of the parameters to classify it in the mineral class, we will not call it mineraloid. Ice is a mineral, without a doubt.
Is Ice a Rock?
Ice is not a rock in its pure form. We define the rocks to check if we can add the ice in this class. Rocks are solids made of different minerals and occur in nature without human intervention.
A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter.
Is ice a mixture of minerals? No, you can find pure ice in nature in all the places. When a snowflake falls on the ground, it is a mineral but not a rock. There are some places where ice is also a rock.
Most glaciers have ice and other minerals. Glaciers occur naturally as some of them also have rocks in the mixture. They are solid without interventions from humans.
It is okay if some say that glaciers are rocks, but you cannot say that all forms of ice are rocks. The ice in your fridge is neither a rock nor a mineral.
You have made the ice in the fridge using your energy sources. It does not satisfy one of the criteria to be a rock or mineral. It is not natural as you have used your sources to make it.
What Kind of Rock Is Ice?
To know what kind of rock ice is, you need to know about different types of rocks.
- The first class is igneous rocks. These rocks form in the earth’s cores. The extreme heat melts different minerals and combines them to make a peculiar rock known as igneous rock. Granite is the most famous rock in this category.
- The second type of rock is known as sedimentary rock. These rocks are made of skeletons, sand, and plants that lived millions of years ago. Chalk is the most famous sedimentary rock.
- The last type of rock, third, is known as metamorphic rock. This rock forms when there is a rock base and other rocks deposit on it due to heat and pressure. Marble is the most famous metamorphic rock.
We will move now to the most crucial question what kind of rock is ice.
First, we want to remove one choice from the list. You cannot classify ice as igneous rock. You can never form ice from the heat of the earth’s core.
The ice will become water, and water will become gas at this temperature. After removing the igneous rock class from the list, we have two categories remaining.
Most experts believe that we can classify ice in the sedimentary rocks category and metamorphic rocks category on different occasions. We can take the example of glaciers.
Most characteristics of the glaciers match the metamorphic rocks. Glaciers are formed when there is a layer of ice on the bottom, and the snowfall on it increases the thickness of the glaciers.
Every time snow falls on the glaciers; it becomes part of it due to the pressure of the snow coming after one layer. Air can also exert pressure on the snow as it shuffles snowflakes to deposit on the bottom layer.
As the new layer deposits on the existing layer, the bottom layer solidifies. The way of the glacier formation is the perfect example of metamorphic rocks.
To classify the ice in the sedimentary rocks category, we need to understand how the sedimentary rocks form. They form when small mineral and rock particles come to a place and merge due to pressure.
The bottom layer of the glacier acted as the base layer for the metamorphic rock formed by the process of sedimentation. When the wet air comes to the ground, it forms a thin layer of frost.
If the environment is suitable, the thickness of this layer increases. When snowflakes come to this layer of ice, they will deposit on it. It is a way of sedimentary rock formation.
The best way to classify the ice is to add it to the metamorphic rock class. It is also suitable if you add it to the sedimentary rock class.

Does that Mean Water is Lava?
It is impossible to call the water lava because of many factors. We need to define the lava first to understand the concept.
Lava comes from the volcanos in semisolid form. It does not flow freely without a steep decline. Lava is not liquid at room temperature.
Water forms when the ice melts. It does not come from the erupting volcanos. The water is liquid at room temperature. You can drink the water because it is liquid. It is easy for the water to move at a minor decline.
The most crucial difference between the lava and the water is consistency. Water has a low consistency as you can move it easily around.
Lava is a thick material that does not move with less force. The boiling point of the water and lava is different. Lava has a melting point of thousands of degrees celsius.
The water does not require heat to become liquid as you will find it in liquid from everywhere. Water and lava are two different entities as there are very few things similar between them.
