Quarry tile is extensively used for floors where a very durable material is required. It can be used either indoors or outdoors, although freeze-resistant grades of tile should be used outdoors in climates where freeze-thaw action occurs. Quarry tile is used less often as a wall finish and is occasionally used for countertops, although the wide grout joints can make cleaning of countertops difficult. Most commercial kitchens require a quarry tile to be used because of its slip resistant and non-porous properties.
Quarry tile is a building construction material, usually ?1/2 to ?3/4 inch (13 to 19 mm) thick, made by the extrusion process from natural clay or shales. Quarry tile is manufactured from clay in a manner similar to bricks. It is shaped from clay, and fired at a high temperature, ~2,000 F°.
