What is Jasperware?
The Wedgwood portrait medallions are made from jasperware, a type of fine-grained, unglazed stoneware introduced by English potter Josiah Wedgwood.
White clay is used to make jasperware. Vibrant colours such as blue and green are created by adding metallic oxides. White decorations were either painted with different glazes, or made in separate moulds then added to the piece.
