Elevate Your Art with Special Effects, Surface Depth and Tactile Brilliance!

Cone 6 oxidation (first photo): Black 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 (second photo): Texture flattens, color remains black.

Mayco's Stoneware Specialty Glaze

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.

General Use

Use Mayco Stoneware Glazes on any midrange clay body. These glazes are intended for use at cone range 5/6 but are also stable and pleasing at cone 10. Can be used in oxidation, reduction or other alternative atmospheric firing conditions. Always test prior to use.

• Shake vigorously upon opening. Continue to shake and stir to increase fluidity to the consistency of cream.
• For shown chip results, apply directly to bisqueware.
• Apply 2-3 coats. Allow glaze to semi-dry between coats.
• The thicker the application, the more textured the surface will be.
• If the glaze does not crack on the piece before firing, it will not crack after firing.
• Due to the surface texture, we recommend that these glazes only be used on decorative surfaces.
• Mudcrack can be applied over Stoneware Gloss glazes for a slightly flatter texture. *See photo below.
• Mudcrack can be used in combination with other Stoneware glazes to achieve different textures and effects. We recommend testing prior to use.
