A fine hard stoneware, it was developed by Josiah Wedgwood in England in the late 18th Century and said to be perfected in 1774. It is noted for its matte finish and variety of colors, although the most famous is a rich blue, known as Wedgwood Blue. The name comes from jasper, which are the mineral oxides used for staining. Classical white figures are applied after the coloration. Source: Wikipedia: Jaspwerware
