Marble is a kind of building material with strong plasticity. It can be processed into plates or columns of any shape. It can also be shaped, rounded, etc. How do you know how marble is formed? Formed from igneous rock, it is a steel hard crystalline marble formed of feldspar, quartz and interspersed with one or more black minerals, which are structurally flat.
Granite is mainly composed of quartz, feldspar and mica. The feldspar content is 40%-60%, and the quartz content is 20%-40%. The color depends on the type and quantity of the components contained. Granite is a rock with full crystal structure. The fine granite has fine and uniform grain structure, compact structure, high quartz content and bright feldspar luster.
Granite has a high silica content and is an acidic rock. Some granites contain trace amounts of radioactive elements and should be avoided indoors. Granite structure is dense, hard texture, acid and alkali resistant, weather resistant, and can be used outdoors for a long time.
