Sandstone - an overview ScienceDirect Topics

Sandstone is made of particles of silica, bonded together either by more silica or by calcium carbonate (CaCO 3). Like pottery, it is porous. Like pottery, it is porous. The difference lies in the way the bonding phase formed: it is precipitated from solution in ground water, rather than formed by melting.
