ironstone china
Stone china is a dense hard white ceramic that does need a glaze. Its smooth surface results from the high percentage of glass forming material in the body recipe. Patented in 1800 by William & John Turner, their version was known as “Turner’s Patent”. The Turner factory closed in 1806. The factory of the mason family first produced their famous “Ironstone china”, with Spode producing his own “Stone China” about 1813. These later version were usually decorated and glazed and resembled dense, hard earthenware.
