Calcite

$60.00

Composition: Calcium carbonate (CaCO₃).
Color: Typically colorless or white, but can also be found in shades of yellow, green, blue, or pink due to impurities.
Crystal System: Trigonal, often forming rhombohedral crystals.
Properties:
- Hardness: 3 on the Mohs scale.
- Cleavage: Perfect cleavage in three directions, leading to rhombohedral fragments.
- Reactivity: Reacts vigorously with dilute hydrochloric acid, producing carbon dioxide.
Occurrence: Commonly found in sedimentary rocks, especially limestone and marble, as well as in hydrothermal veins.
Uses:
- Widely used in the construction industry (e.g., as limestone).
- Important in the production of cement.
- Used in the manufacture of glass and ceramics.
- Plays a significant role in the geological carbon cycle.
