Ceramics, artware

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.
