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.
