Mayco Glazes Brushable Mudcrack

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

Stoneware Classic & Matte Glazes: Stir well. Apply to soft-fired bisque (cone 04/06). Apply one, two or three coats depending on the result desired. Allow each coat to dry before applying the next coat. Fire from cone 5/6-10. See label for additional firing information for individual glazes and cone 10 performance.

Stoneware Crystal Glazes: Crystal glazes are designed to expand upon the surface with dazzling bursts of colour. Crystals will settle to the bottom of the jar and will need thorough mixing prior to initial use and in between each coat. Apply two to three coats using a fan or hake brush. While the glaze is wet, use your brush to redistribute crystals to achieve balanced coverage. Over application of the crystals can cause pinholing or running. Avoid placing crystals near the bottom third of a vertical piece as they may cause additional movement during firing. See label for additional firing information for individual glazes and cone 10 performance.

Stoneware Gloss Glazes: Stoneware Gloss glazes can be used in design, all over coverage and are the ideal product for intermixability at mid-range temperatures. The integrity of your design will remain unchanged as these glazes are incredibly stable and will not move or combine with surrounding colours. See label for additional firing information for individual glazes and cone 10 performance.

HELPFUL HINTS

STONEWARE CRYSTAL GLAZES

Crystals will settle to the bottom of the jar and will need a good mixing prior to initial use. Re-stir between each coat. Stir with palette knife or another unpainted tool.

Over-application or heavy deposition of the crystals can cause pinholing or running.

Crystals will flow more than the base glaze. During your last coat, use your brush to evenly distribute the crystals over the top two-thirds of the piece and move away from the bottom third.

While the glaze is wet, you can use your brush to redistribute the crystals to achieve balanced coverage.

When storing a crystal glaze, you may consider storing upside down to facilitate crystal dispersion on the next use.
