Sandstone is a sedimentary rock made of grains of sand (defined as 1/16 mm to 2 mm sized particles) that have been naturally cemented together. Grains in sandstones are unfused, and some of these grains can be dislodged by rubbing across the rock. Sandstone represents ancient stream, deltaic, or beach deposits.
Uses for sandstone include: liners for steel furnaces; as building stone; as an abrasive; for golf-course trap sand; and in making glass, computer chips, fiberglass, TV screens, and paint. Most sandstone in Ohio is found in the eastern half of the state in rocks of Devonian, Carboniferous (Mississippian and Pennsylvanian), and Permian ages.
Composition: Quartz (SiO2) grains, feldspar grains, and other rock fragments with various compounds as cementing materials.
