Its color depending on the mineralogy and chemistry of rocks, from pink to dark gray or even black, is variable. The stones of the heaviest rock with a density of 2. 75 grams per cubic centimeter. Granite is one of the strongest and hardest rocks are therefore widely used as a building material. Resistance to corrosion makes extensive use of this stone is in the lab. Resistance and high hardness of the stone allows the sheets with a thickness of only a few millimeters of the stone building. It should be noted that the Latin root word is granite. Stone is cooling the molten mass is formed. Granite symbol of hardness, resistance and durability. Granite white, gray, Portuguese, green, black, red, etc. are . Granite harder than limestone but are more uniform. And do not easily scratch granite on their resistance to high temperatures. Granite works best on the pavement outside and in places that are exposed to traffic is high but it can be used in exterior and roads inside the building and the stairs can be used most of the rocks of the Central Asian countries such as India, China, Taiwan and Vietnam purchased and of high quality. this type of stone contains two types of natural color made from a variety that can rock with peach and peas and red, Black Galaxy, a chance to Black, Carmen red, Baltic Brown, Maple red, Jvparna, multi Color Red Volgabo, Bidasr brown, green Bidasr, Bidsar Brown, Silver Pearl pointed.
