Sandstone

DEFINITION

A sedimentary rock formed by the compacting of grit or sand with a high silica content bound in a natural cement ? the silica itself. Many sandstones are soft and easily eroded, but some are quite hard and durable. Sandstone is generally more difficult to carve than limestone, for the particles wear down the metal of the chisel. Some sandstone can be polished.
