Fossil Rock


Cone 6 oxidation (large photo): Geologically inspired with mottled earth tones, Fossil Rock is an opaque, tan, matte glaze that breaks over texture.

Cone 10 reduction (small photo): Glaze shifts ivory with soft gray and warm brown marbling. Breaks slate gray over texture. Glaze remains stable.

TIP: This glaze is generally stable at 3 coats. Additional coats or increased application thickness may result in glaze movement. We recommend firing our matte glazes to cone 6 to produce a satin matte finish.



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.
