Mayco Stoneware Glazes
Mayco’s Stoneware glaze assortment, including Classic, Matte, Crystal, and Gloss, offers a variety of finishes, textures and endless possibilities for glaze combinations. Available in both liquid and dry. Chips shown have been fired to cone 6 on a white stoneware body.
CLASSIC, MATTE, CRYSTAL, AND GLOSS
One of the most distinctive traits of Mayco’s Stoneware is that the glazes provide consistent performance and intriguing visual interest. They are best known for being receptive and favorable to the user during both application and firing. Mayco Stoneware glazes are friendly to the user in application, layering and firing. Many glazes will break over textures, revealing secondary colors and shades. The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results.
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 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 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 colors. 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 other 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.
- You can find the information about the base glazes of all our Stoneware Crystal glazes on the label.
STONEWARE MATTE GLAZES:
- SW-136 Weathered Blue, SW-137 Storm Gray and SW-138 Lemon Meringue are unique glazes that change in appearance with number of glaze coats. One coat will display more color while additional coats will increase mottling and white variegation.
CONSISTENT PERFORMANCE AND CONTROL
Mayco Stoneware glazes offer the depth, sophistication and reliability to artists working from mid-range to high-fire temperatures.
GLAZE COMBINATIONS
Mayco Stoneware glazes work great layered both under or over other glazes. Artists can achieve incredible finishes with a simple combination of two glazes
ALL OVER COVERAGE
Used alone, Mayco Stoneware glazes produce beautiful color variations, deepening with additional coats. One coat will allow more of the clay body to show through the glaze. Subsequent coats deepen the color. Gloss Glazes are the ideal product for brightly colored dinnerware.
STONEWARE WITH STROKE & COAT®
Many Stroke & Coat® glazes perform well at mid-range. Darker colors such as red, orange, yellow, blue and green may darken compared to their cone 06 results. Lighter colors such as tan, purple and pink will fade.
STONEWARE WITH ELEMENTS™
Many Elements™ and Elements™ Chunkies create beautiful effects when used with stoneware at mid-range. Elements™ will be quite fluid and move during the firing process so keep away from the bottom of the ware.
STONEWARE WITH JUNGLE GEMS™
Jungle Gems™ glazes perform at midrange for very interesting results. Crystals will have additional movement at higher temperatures and will act more as a blending agent.
STONEWARE WITH DESIGNER LINER
Designer Liner enables artists to achieve crisp, non-moving linework from cones 06 – 6 temperatures. To ensure sharpness in line quality, use a non-moving translucent or clear glaze over the top of Designer Liner.
CONE 10 FIRING OR ALTERNATIVE ATMOSPHERIC FIRING CONDITIONS
Mayco Stoneware glazes are intended for use at cone 5/6, but many are also pleasing and stable at cone 10 oxidation, reduction or other alternative atmospheric firing conditions, such as wood, salt or raku. Cone 10 color performance can also be found on the left side of the stoneware glaze label. The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results. Due to variability, we recommend testing prior to application to artwork.
USE OF DIFFERENT CLAY BODIES
Glazes will perform differently based on clay body used. We recommend testing prior to application to artwork.
IN DESIGN AND MAJOLICA
Mayco’s Stoneware Gloss glazes are incredibly stable and opaque in design work and for majolica techniques at mid-range temperatures. The integrity of your design will remain unchanged as these glazes will not move or combine with surrounding colors. Lighter colors can be used over darker colors, remaining bright and opaque.
OVER TEXTURE
Most Mayco Stoneware glazes will break over textures, revealing secondary colors and shades. These glazes heighten surface details where they gather and pool.
STONEWARE CLASSIC & MATTE GLAZES: Mayco Stoneware Classic glazes are a mixture of AP Non-Toxic and CL (Health Caution) label. Please review the individual color label for health classification and any appropriate warnings. All but one (see below) of the Stoneware glazes in the Classic line are Food Safe, according to FDA standards. Note: Finishedware producers may be required to have their ware food safe tested prior to introducing into commerce.

SW-132 Mirror Black, SW-182 Antique Brass, SW-164 Satin Patina, SW-185 Rainforest, SW-186 Azurite, SW-187 Himalayan Salt, and SW-188 Landslide are not Dinnerware Safe due to the durability of the fired glaze. Some glazes, regardless of surface texture or porosity of underlying clay body, will be designated as not suitable for dinnerware as the fired glaze surface is not durable and can be impacted by contact with food or liquids. While it may not be harmful, it is certainly not desirable. SW-132 Mirror Black, SW-182 Antique Brass, SW-164 Satin Patina, SW-185 Rainforest, SW-186 Azurite, SW-187 Himalayan Salt, and SW-188 Landslide are recommended for ornamental use only.

The Stoneware Crystal glazes are also Dinnerware Safe when used according to manufacturer’s directions and fired to the clay body’s vitrification temperatures. However, discretion and judgment should be used if the glaze surface is heavily textured, less from a safety and more from an aesthetic perspective.
