Blue Jasper Ware

  Jasper is white in its natural state and is stained with metallic oxide colouring agents. The most common shade is pale blue, but dark blue, lilac, sage green, black, and yellow were also used. The earliest jasper was stained throughout and was known as "solid," whereas the later varieties were coloured only on the surface and were known as "dip."
 Decorations, in the Neoclassical style and usually white, were made in separate moulds and applied to the body of the piece. Objects made of jasper were varied and included vases, plaques, tableware, cameos, furniture mounts, and portrait medallions.
