Cone 6 oxidation (larger image): White Mudcrack is a high-texture glaze that forms a raised, cracked surface. The thicker the application, the more textured the surface will be.

Cone 10 reduction (smaller image): Texture flattens, color remains white.

Mudcrack was developed to create a highly-texture raised and cracked surface. The thicker the application, the more textured the surface. Mudcrack can be directly applied to bisqueware or in combination with other mid-range glazes. For shown results, apply directly to bisqueware. Heavy application may cause unfired glaze to release from bisqueware. If glaze is thick in the jar, vigorous stirring and shaking will increase fluidity. The amount of texture and cracking that is produced with these glazes is directly a result of how thick the glaze is applied. A thinner application will result in a smoother surface with very fine cracks. A thicker application will result in larger cracks and more tactile texture.

Chips 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.
