Calcite is a kind of calcium carbonate mineral, which is the most common natural calcium carbonate and widely distributed. Calcite crystals have a variety of shapes, and their aggregation can be a cluster of crystals, or granular, massive, fibrous and so on. Many square fragments can be obtained by knocking calcite, so it’s named calcite.

The color of calcite varies with the impurities contained in it. But it’s usually white or colorless. The colorless and transparent calcite is also called Iceland spar, through which you can see the double image of an object. Therefore, Iceland spar is an important optical material.
Calcite is the main mineral of limestone and marble, which has many functions in production and daily life. It’s known that limestone can form karst caves, and the stalactites, stalagmites and white marble in the caves are actually made of calcite.
