Description
White refractory paste with 40% medium chamotte 0-1.5 mm. Designed for artistic ceramics, it is ideal for larger sculptures, murals and large pieces in Raku. The high chamotte content gives character to the ceramic piece and provides it with excellent behavior during drying and firing. Its particular ivory white color when fired is highly appreciated and provides the excellent base for color development in enamels and coloring oxides. Available in extruded plastic paste.
