Cone 6: Lava Rock is formulated to produce a dark brown satin glaze mottled with golden flecks. Lighter coats will produce a semi-opaque dark brown finish with little to non-visible tan flecks. Use three+ coats to produce a more prominent mottled effect with the glaze breaking over texture.
Cone 10: Color darkens.
Stoneware matte glazes range from solid shades to those that create interesting color variations as they move and break. Application thinkness is the key to making mattes work for you.
