TIP: This glaze is stable at 3 coats. Additional coats or increased application thickness may result in movement. We recommend firing our micro glazes to cone 6 oxidation to reach crystalline development. Micro-Pearl achieves a stable, semi-opaque, frosted white result with a pearlescent satin finish when fired to cone 5. Can be used in oxidation or reduction firings. Results may vary. The choice of clay body, thickness of application, firing process, and temperature will greatly affect the fired results. Always test your application on your clay body in your kiln environment. 

Tips for Micro Glazes (SW214 - 218):

• Micro is short for micro-crystalline which is a glaze that develops small crystallization from the zinc and silica during the cooling process. These glazes can be fired from cones 5-10, but we suggest a hot cone 6 with a fast cool in a loosely packed kiln for optimum crystallization.

• While Mayco’s Stoneware Crystal glazes contain glass frit in the jar, Micros do not contain a glass crystal, rather, the effect is created by the glaze itself during the firing process.

Tips for Crystals:

• Crystal glazes are designed to expand upon the surface with dazzling bursts of color.

• 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 brush. While the glaze is wet, use your brush to redistribute crystals to achieve balanced coverage. Overapplication of the crystals can cause pinholing or running.

• Crystals can create movement. Avoid having a heavy concentration of crystals near the bottom of your piece.

Mayco’s line of Stoneware Glazes are available in a beautiful array of colors, tints and tones. These glazes were developed to perform from mid-range (cone 5/6) to higher fire (cone 9/10) temperatures.  Stoneware classic glazes offer the depth, sophistication and reliability to artists working from mid-range to high-fire temperatures. Many glazes will break over textures, revealing secondary colors and shades. Used alone, stoneware glazes produce beautiful color variations. One coat will allow the clay body to show through the glaze and two to three coats deeper the color. The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired finish--we recommend that glazes always be tested on your clay body.  

Mayco’s Stoneware Glazes are Food Safe, Non Toxic and Non Hazardous when used according to manufacturer's directions.
