"Clay associated with the coal measures of the Carboniferous System of sedimentary rocks. A few deposits are residual clays similar to china clay. Fireclays are often refractory clays and are used for firebricks. The name gives this impression but there are fireclays which vitrify below 1300°C (2372°F). These are used for drainage pipes, building bricks, sanitary ware and stoneware. Grog is usually fired and ground fireclay."
