Granite is formed by igneous rock, which is a kind of hard crystal lens stone. It was originally formed of feldspar and quartz and mixed with one or more black minerals. They are all arranged in a flat structure.
Granite is mainly composed of quartz, feldspar and mica. Among them, the feldspar content is 40% -60%, and the quartz content is 20% -40%, and its color depends on the type and quantity of the ingredients. Granite is a rock with a fully crystalline structure, high-quality granite has fine and uniform grains, tight structure, high quartz content, and bright and bright feldspar.
Granite has a high silica content and is an acid rock. Some granites contain trace amounts of radioactive elements, and such granites should be avoided for indoor use. The granite has a compact structure, a hard texture, good acid and alkali resistance, and good weather resistance, and can be used outdoors for a long time.
