Quartz, feldspar and mica are granite, right?
Granites belong to igneous rocks, which are formed by the eruption and intrusion of underground magma, cooling crystallization, and granitic metamorphic rocks. Having a visible crystalline structure and texture. It consists of feldspar and quartz, with a small amount of mica and trace minerals, such as zircon, apatite, magnetite, ilmenite and titanite etc.. The main component of granite is silica, and its content is about 65% - 85%.Quartz stone is a kind of short board which is produced by the stone plate manufacturers at present. Because of the main content of quartz is more than 93%, it is called quartz stone.Quartz is one of the main components of granite, so quartzite should be considered as artificial granite.Granite is mainly composed of quartz, feldspar and mica
Bulk mica is usually reddish brown, because of impurities, the most obvious feature is flat, layered, single layer stripped off, thinner than paper, close to transparent, there is bright reflection, there is a hot electric iron.
Feldspar is milky, relatively crisp, irregular texture, is the raw material of porcelain.
Quartz according to the content of impurities from large to small, milky white, translucent and transparent, is the raw material for making glass, pure and transparent quartz stone is crystal stone, the chemical composition is silica.
