Mayco’s Stoneware Dry glaze assortment, including Classic, Matte, Crystal, and Gloss, offers a variety of finishes, textures and endless possibilities for glaze combinations for Cone 6-10 firing. Mayco’s Stoneware glazes are available in both liquid pint and dry glazes in 5lbs packs. Dry formulas are added to water and used in buckets for dipping or pouring techniques. Many functional potters prefer dipping to painting for even coverage. The colors and formulas are identical in dry form, minus the added organic gums. Mayco Stoneware Dry glazes (SD is the prefix, it stands for Stoneware Dry) are great for pieces with a lot of surface texture and for layering techniques. Chips shown have been fired to cone 6 on a white stoneware body.
Dry mix products: Always wear a NIOSH approved respirator when handling dry glazes. Gently tumble unopened bag to redistribute materials. Sieving is not necessary. Mix one 5lb bag of dry material into 4-5 pints of water. Stir thoroughly with a wood paddle, stick or drill with mixing attachment. We recommend using 15lb of dry glaze to start a 3 gallon bucket and 25lb to start a 5 gallon bucket. Add additional water until desired specific gravity is reached. Our recommended Specific Gravity is in the range of 1.47 to 1.51. Stir well before each use. Immerse the ware for 1-2 seconds. We suggest using dipping tongs. One dip of Mayco Dry is equivalent to 3 coats. Shake excess glaze off gently. Allow the glaze to dry before applying additional coats if desired. When applying Stoneware Dry Crystal glazes, use a cup or ladle to pour the glaze over your piece. While the glaze is wet you may use a fan brush to evenly distribute the crystals; avoid heavy crystal loading on the bottom 1/3 of your piece. Fire from cone 5/6-10. Tip: Save your bag or log the lot number for if you have any questions for our technical team. Tip: Apply AC-302 Wax Resist to the bottom for easy dry foot clean-up.
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.
CONSISTENT PERFORMANCE AND CONTROL
Mayco Stoneware glazes offer the depth, sophistication and reliability to artists working from mid-range to high-fire temperatures.
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.
DIPPING WITH STONEWARE DRY GLAZES
Use Mayco Stoneware Dry glazes (SDs) for fast dipping and layering, creating natural flowing effects. Fine and uniform particle size and a thorough dry mixing process make Mayco Stoneware Dry glaze consistency so perfect that sieving is optional.
POURING WITH STONEWARE CRYSTAL DRY GLAZES
For fast glazing and flowing effects, we recommend using Mayco’s Stoneware Crystals Dry mix glazes (SDs). Due to the crystals settling to the bottom, we recommend mixing thoroughly and pouring the mixed glazes onto your piece with a pour container or pitcher. Over application in the same area may cause crystals to fall off.
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.
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. With the exception of those noted below, The Stoneware Classic and Matte glazes are also Dinnerware Safe when used according to manufacturer’s directions and fired to the clay body’s vitrification temperatures. 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.

Note: Finishedware producers may be required to have their ware food safe tested prior to introducing into commerce. 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.
STONEWARE GLOSS GLAZES: Mayco Stoneware Gloss glazes are AP Non-Toxic, Food Safe, and Dinnerware Safe, when used according to manufacturer’s directions. Note: Finishedware producers may be required to have their ware food safe tested prior to introducing into commerce.
