Granite is a kind of igneous rock, also known as acid crystalline plutonic rock, which belongs to hard stone. It is made of feldspar, quartz, and a small amount of mica. Granite is dense and has a granular structure. The main component of granite is silicon dioxide, which has a hardness of 6 to 7 according to Mohs hardness. Natural granite has different shapes and needs to be crushed to meet the demand for materials in various fields. After processing and polishing, the surface of granite will form a beautiful speckled pattern with different shades of color. The pattern is characterized by fine and uniform grains, with star-liked mica highlights and sparkling quartz crystals.
