A type of white porcelain, with a slightly granular surface, which resembles pure white statuary marble and was used mainly for busts and figures. It was first produced at the Copeland factory in 1844 and the following year the Art Union of London commissioned Copeland to reproduce in Parian ware the work of several leading sculptors of the day. Other factories such as Minton, Wedgwood, and Worcester soon followed suit. A number of manufacturers exhibited very large pieces made in Parian ware at the Great Exhibition, London of 1851. Similar wares were produced on the Continent and in the United States.
