What is the difference between granite and marble? How to identify from the appearance?

Granite is an igneous rock formed by the condensation of magma below the surface, and its main components are feldspar and quartz. Because granite is a plutonic rock, it can often form well-developed mineral particles that can be distinguished by the naked eye, hence the name. Granite is not easy to weather, beautiful in color, and its appearance can be maintained for more than 100 years. Because of its high hardness and wear resistance, it is not only used as high-grade building decoration engineering and hall floor, but also the first choice for open-air carving.

Marble, also known as marble, is recrystallized limestone, and its main component is calcium carbonate. Limestone softens at high temperature and high pressure, and when the minerals in it change, it recrystallizes to form marble. Marble is mainly used for processing into various shapes and plates, making walls, floors, platforms and columns of buildings, and is a precious material for furniture inlay. It is also often used as a material for memorial buildings such as monuments, towers and statues. Marble can also be carved into handicrafts, stationery, lamps, utensils and other practical works of art. Marble is soft, beautiful, solemn, elegant in style and diverse in color. It is an ideal material for decorating luxury buildings and a traditional material for artistic carving.
