A) Joining slip is a clay body that is in a more liquid state used for attaching semi-stiff or leather hard pieces of the same clay body. B) Casting slip is a suspension of clay in water used for casting pottery or sculpture in molds. Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a "mineral aggregate composed of hydrous silicates of aluminium (Al2O3·2SiO2·2H2O) with or without free silica."
