Cone 6 oxidation: Amber Quartz is a warm amber matte glaze that adds accents of tan and brown. The variation of the glaze is dependent on application. The thicker the application, the more homogenous the colour will be. The glaze will break translucent where thinner and pool darker around surface textures.

Cone 10 reduction: Glossy purple/blue is more prominent.

Stoneware matte glazes range from solid shades to those that create interesting colour variations as they move and break. Application thickness is the key to making mattes work for you. Tiles shown are fired flat on a white clay body fired to cone 6 oxidation and cone 10 reduction. The choice of clay body, the thickness of glaze application, the firing process, and temperature will affect the fired results.
