Ceramics, artware glazes

Crystalline glazes contain large crystals which render the surface matt and even attain discernible sizes. They find application mostly in ceramic artware. A matt surface is usually developed by anorthitc or wollastonite crystals which crystallize from glazes of suitable compositions. Additions of ZnO or Ti02 also create a matt surface. 

Spatterware. A type of mottled ceramic artware a white or coloured glaze is spattered irregularly over the dipped glaze before the glost firing. 

Among the many other ceramic applications in which wollastonite can be used are glazed porous ceramics of nearly every kind, dinnerware, ovenware, artware, structural clay products, terra cotta, sanitaryware, chemical stoneware, ceramic-bonded abrasives, refractories, high alumina bodies, spark plugs, electrical porcelains, frits and investment castings.
