Sandstone is a sedimentary rock composed mainly of sand-sized minerals or rock grains.Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone may be any colour, but the most common colours are tan, brown, yellow, red, gray, pink, white and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colours of sandstone have been strongly identified with certain regions.
Stone Sandstone is used for ages, almost since the establishment of habitats and cities, as the basic building material for the construction of bridges, viaducts, church buildings, public housing, etc. as well as applies in the garden and home accessories.
