Jasperware

Jasperware, or jasper ware, is a type of stoneware first developed by Josiah Wedgwood, although some authorities have described it as a type of porcelain. It is noted for its matte finish and is produced in a number of different colours, of which the best known is a pale blue that has become known as 'Wedgwood Blue'. "Jasper" in this context refers to the mineral of that name.
