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.
Cone 6 oxidation (larger image):: Riptide is a satin-matte, opaque, variegated turquoise/green glaze that breaks over texture and develops a glossy finish where thick or pooling.
Cone 10 reducation (smaller image): Glaze shifts grey with white/turquoise variegation. Glaze remains stable.
TIP: This glaze is generally stable. Additional coats or increased application thickness may result in movement. Thin application results in finely variegated color. Variegation is
exaggerated with application thickness. We recommend firing our matte glazes to cone 6 to produce a satin matte finish.
Cone 6: Gray Opal creates a transparent gloss finish. It deepens in color from one coat to three but surface decoration and design remain visible through theglaze even with three coats. The glaze will break and pool around surface textures, creating opportunities for the opalescent character to develop. Cone 10: Color lightens; becomes more transparent. TIP: Thinner application will provide a glossy transparent finish. Thicker application will provide blue white floating. Surface decoration will be visible under the glaze, but if you apply the glaze thick, it could blur your image.
Cone 6: Red Gloss is a highly-pigmented scarlet red gloss glaze. The stable qualities of this glaze make it ideal for design work and full opaque coverage at mid-range temperatures.
Cone 10: Color darkens.
Cone 6: Glacier Blue provides a translucent, light blue gloss color. You will produce beautiful color variations with Glacier Blue without the glaze running off your ware during firing. Designed to provide a hint of color with one coat, deeper color with two to three coats - but remaining translucent. Cone 10: Color lightens. TIP: One coat allows more of the clay body characteristics to appear through the glaze, adding a faint color gloss to the surface. Subsequent coats deepen the blue color but at three coats you will still obtain a translucent fired surface. Four+ coats will produce more opacity and less translucency.
Cone 6: Tea Dust is formulated to produce a rust, semi-gloss glaze mottled with golden flecks. Lighter coats will produce a semi-transparent rust color with little to non-visible gold flecks. Use three plus coats to produce a more prominent mottled effect with the glaze breaking over texture.
Cone 10: Color darkens.
Cone 6: Cinnabar is a rich maroon-red gloss glaze that tends to develop a hazy purple float with heavier application. Cone 10: Color darkens. TIP: One to two coats will produce an opaque maroon-red; three+ coats will produce higher levels of purple float. You’ll produce beautiful color variations with Cinnabar without the glaze running off your ware during a cone 6 oxidation firing.
Peacock Matte develops a matte copper color with various iridescent shades of blue and purple following a proper raku firing. Due to the unpredictable nature of this firing technique, results will vary with every firing.
Cone 6 results: Milk Glass is a glossy, semi-opaque white glaze that breaks transparent over texture. This glaze is stable.
Cone 10 reduction: Color shifts to blue with white float. Remains stable.
Tip: This glaze works well in combination with other glazes.
Cone 6 results: Sparkle Black Engobe fires matte black with metallic specks. Specks may produce texture. Highly stable.
Cone 10 reduction: No change to base color. Specks bloom and become matte. Remains stable.
Tip: To enhance the sparkle and improve texture, use your fingers to burnish/polish the surface of the ware before the last layer is dry. Polishing is not needed when used in combination.
Cone 6: Night Moth is an opaque gloss glaze with crystals that bloom into sage and gray.
Cone 10: No change. TIP: SW-508 Black Gloss is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-508 Black Gloss with a third coat of SW-181 Night Moth.
Cone 6: Sandstone is a matte, off-white glaze that contains a variety of brown crystals that melt during the firing. Thicker application and heavy crystal concentration will produce more glossy blue/purple variation.
Cone 10: Color darkens. Glossy blue/purples become more prominent. TIP: SW-172 Macadamia is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-172 Macadamia with a third coat of SW-176 Sandstone.
Cone 6: Galaxy is a semi-transparent charcoal colored gloss glaze that contains a three-tone white, orange, and blue crystal. As the crystal melts, a brilliant bloom of white, orange, and blue appears. The glaze is reminiscent of a star being born. Cone 10: Crystals and base showcase more blue hues. Crystals melt. TIP: SW-209 Charcoal is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-209 Charcoal with a third coat of SW-156 Galaxy.
Cone 6: Blue Splatterware is a white, semi-matte glaze that contains a blue crystal. As the crystal melts it creates small blue blooms that cause the glaze to resemble the look of 19th century enamelware.
Cone 10: Crystals become less defined. TIP: SW-141 White Matte is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-141 White Matte with a third coat of SW-152 Blue Splatterware.
Cone 6: Lime Shower is formulated to produce a vibrant chartreuse gloss glaze with dark green and white crystals. Light coats will produce a semi-transparent finish in the base glaze with fewer crystals. Use three or more coats to produce an opaque green float with more saturation of crystals. At cone 5, this glaze will produce a matte sepia finish with little breaking over texture. Cone 10: Color becomes less vibrant. Crystals melt. TIP: SW-253 Green Opal is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-253 Green Opal with a third coat of SW-148 Lime Shower.
Cone 6: Aurora Green produces a mottled aqua gloss glaze with light brown and large black crystals. As the crystals melt, bursts of blue and brown will develop. Cone 10: Color changes to a variegated pink/blue/green. Crystals become less pronounced. TIP: SW-108 Green Tea is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-108 Green Tea with a third coat of SW-146 Aurora Green. Due to the large sized crystals in Aurora Green they often reside in the bottom of the glaze; be sure to stir well or pour the glaze out onto a plate to make them more accessible.
Cone 6: Midnight Rain is a blue-green breaking gloss glaze that contains a black crystal. As the crystal melts and moves, a black oil-like streak is created in the glaze.
Cone 10: Crystals melt and integrate into base glaze, darkening the color. Increased movement. TIP: SW-100 Blue Surf is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-100 Blue Surf with a third coat of SW-115 Midnight Rain.
Cone 6 oxidation:Peppered Plum is a glossy, opaque, burgundy glaze that breaks over texture and develops a warm taupe float; small opaque black crystals are featured with large semi-transparent burgundy crystals.
Cone 10 reduction: Glaze darkens, and crystals soften. Large crystal shifts to opaque red. Light application recommended.
TIP: SW-113 Speckled Plum is the base glaze. For a lighter crystal effect, apply 1 coat of SW-191 Peppered Plum over 2 coats of SW-113 Speckled Plum. This glaze is stable, even with heavy application. Light application will result in a more homogenous burgundy. Warm taupe float develops and intensifies with glaze thickness.
Cone 6: Emerald provides a translucent green gloss color. You will produce beautiful color variations with Emerald without the glaze running off your ware during firing. Designed to provide a hint of color with one coat, deeper color with two to three coats - but remaining translucent. Cone 10: Color changes to red in a heavy reduction. TIP: One coat allows more of the clay body characteristics to appear through the glaze, adding a faint color gloss to the surface. Subsequent coats deepen the green color but at three coats you will still obtain a translucent fired surface. Four+ coats will produce more opacity and less translucency.
Cone 6: Abalone is formulated to produce a breaking white and mauve semi-gloss glaze. Light applications will produce a more white semi-gloss finish. Use three+ coats to achieve semi-gloss Abalone finish. Clay body characteristics will be visible through this glaze. Cone 10: Color darkens to purple.
Cone 6: Purple Mint is a gloss glaze that produces greens and purples, reacting strongly to surface textures. On flat, smooth surfaces lighter coats will find greens breaking through a light layer of purple. As more coats are added purple will dominate the fired finish. On textured surfaces green will almost always appear on and around incised and raised areas. Cone 10: Color changes to a variegated blue. TIP: The thinner the application the more green the glaze will appear. The thicker the application the more purple the glaze will be.
Cone 6: Oxblood is a milky gloss and transparent glaze that pools red. Heavier application will produce more red. Cone 10: Gloss finish is enhanced and less milky. Red pooling is brighter. Tip: Must be applied thick for red variation to appear.
Cone 6: White Matte is formulated to produce a smooth matte surface. Light coats will allow clay body characteristics to appear through the glaze (especially on dark and speckled clay bodies).
Cone 10: No change. TIP: A true matte finish at cone 5/6 with no movement. Thicker application, three or more coats, will produce a more opaque finish.
Cone 6: Root Beer provides translucent, rich, brown gloss color. Designed to provide a hint of color with one coat, deeper color with two to three coats - but remaining translucent. Cone 10: Color darkens. TIP: One coat allows more of the clay body characteristics to appear through the glaze, adding a faint color gloss to the surface. Subsequent coats deepen the brown color but at three coats you will still obtain a translucent fired surface. Three+ coats will produce more opacity and less translucency. This glaze may have some mobility with thicker applications.
Cone 6: Pink Matte is a semi-opaque matte pink glaze. Lighter coatings will allow body characteristics to appear through the glaze (especially on dark and speckled clay bodies).
Cone 10: Changes to a soft pink translucent gloss. TIP: Lighter coatings will allow body characteristics to appear through the glaze (especially on dark and speckled clay bodies). Thicker application, three or more coats, will produce a more opaque finish.
Cone 6 oxidation (first image): Crackle White is a bright white gloss glaze that develops a fine crackle pattern. Works well on stoneware and porcelain bodies and produces crackle patterns at midrange temperatures. Use India ink to highlight or accentuate crackle patterns.
Cone 10 reduction (second image): Turns an orange-brown and pools white in texture when thick. The glaze does not crackle.
Cone 6 oxidation (third image): Crackle Matte Clear is a soft matte, semi-transparent glaze that develops a fine crackle pattern.
Cone 10 reduction (fourth image): No Change.
TIP: A minimum of two coats are needed to develop a crackle pattern. To highlight the crackle pattern, after firing, wipe black acrylic or ink over the ware and wipe off, allowing the ink to fill the cracks.
Cone 6: Wrought Iron creates an intermittent, dappled black gloss-matte finish that is reminiscent of high fire oil-spot glazes. Typically, oil-spot glazes are thickly applied and require some reduction during the firing to achieve the oil-matte effects; Wrought Iron does the job with just two coats in a cone 6 oxidation firing.
Cone 10: Color changes to a dark metallic gray.
TIP: The thinner the application the more brown the glaze. The thicker the application the more black the glaze. This glaze is not completely matte, but will have a matte finish with variation of gloss. Due to the high manganese content, there is a chance of bubbling on a speckled clay body.

Cone 10: Glossy purple/blue is more prominent. Increased movement. TIP: SW-173 Amber Quartz is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-173 Amber Quartz with a third coat of SW-180 Desert Dusk.
Cone 6: Robin’s Egg is a greenish-blue matte glaze that contains a sand-colored crystal. As the crystal melts, a small sandy-brown bloom will appear in the glaze, producing a mottled, textured finish.
Cone 10: Semi-gloss finish with variegated blue/light blue and crystals. TIP: SW-105 Frost Blue is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-105 Frost Blue with a third coat of SW-116 Robin's Egg.
Cone 6 oxidation: Micro Jade is a glossy, translucent, jade green glaze with a turquoise float that breaks over texture. Blooms of shimmering bronze micro-crystallization will develop during the firing process.
Cone 10 reduction: Glaze turns to a variegated brown. TIP: This glaze is fluid at 3 coats. Recede application to avoid unwanted runoff. Due to the translucent nature of this product, be aware of your application consistency and thickness to avoid streaky brushstrokes. We recommend firing our micro glazes to cone 6 oxidation to reach crystalline development. Micro Jade achieves a stable, semi-opaque olive result that breaks over texture and has 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.
Cone 6 oxidation (larger image): Dark Brown Engobe fires matte brown. Engobes are used to coat your clay body to your preferred finish/color and are a great base to achieve in your glaze results. Cone 10 reduction (smaller image): No change. Tips: Can be applied to wet clay, greenware or soft fired, cone 04 bisque. Engobes are often used for a variety of decorative techniques, such as sgraffito and majolica. Fires matte. Apply clear glaze to intensify color or for use on dinnerware. Engobes will impact glaze results when used as a base. Engobes are used to change the color of your clay color surface without cross contamination and easy clean up in your studio. 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.

Cone 10: Color changes to green where thin/breaking and remains dark blue where thick/pooling. Increased movement. Tip: This glaze can be very mobile; Recede coats to avoid run off on vertical pieces and practice caution in combination. Note: Not recommended for dinnerware due to surface durability.
Cone 6: Blue Opal is a medium blue semi-transparent to fully opaque gloss glaze. Thinner applications create a transparent blue haze; thicker coatings produce an opaque finish. Surface textures can cause the glaze to collect and produce streaks of greyish blue. Cone 10: Becomes more transparent. Can produce red mottling in a heavy reduction. TIP: Light applications on brown and buff bodies will produce a transparent green-blue gloss finish. Thinner application will provide a glossy transparent finish. Thicker application will provide light blue floating. Surface decoration will be visible under the glaze, but if you apply the glaze thick, it could blur your image.
Cone 6: White Opal forms a clear- to- milky white gloss surface. One coat produces the clearest finish; subsequent layering increases the incidence of a white precipitate forming. Prominent white to bluish-white colors will emerge where the glaze pools and gathers around surface texture. Cone 10: White variation lessens leaving a transparent gloss with white pooling. TIP: White coloration is more visible on darker clay bodies (Buff, Manganese Speck). Thinner application will provide a glossy transparent finish. Thicker application will provide white floating.
Cone 6: Melon provides a translucent, light coral gloss color. You will produce beautiful color variations with Coral without the glaze running off your ware during firing. Designed to provide a hint of color with one coat, deeper color with two to three coats - but remaining translucent. Cone 10: Color lightens. TIP: One coat allows more of the clay body characteristics to appear through the glaze, adding a faint color gloss to the surface. Subsequent coats deepen the coral color but at three coats you will still obtain a translucent fired surface. Four+ coats will produce more opacity and less translucency.
Cone 6: Mirror Black creates a highly reflective, metallic black gloss finish. On some vertical surfaces and around surface textures, minor matte effects can be seen; all other applications result in the formation of a black, metallic mirror. Cone 10: Finish flattens. Color remains. Increased movement. TIP: This glaze WILL move. Take care when using on vertical pieces – reduce glaze thickness towards the bottom third to minimize run-off.
Cone 6: Black Gloss is a highly-pigmented true black gloss glaze. The stable qualities of this glaze make it ideal for design work and full opaque coverage at mid-range temperatures. Glaze turns to satin gloss at cone 5 and high gloss at cone 6.

Shake well. Apply 2-3 coats to wet clay, greenware, or cone 04 bisque for use in design or solid coverage.
Fundamentals® have a firing range from cone 06 to cone 10. If the form you are painting has texture, dab excess
color out of the texture, and never allow the glaze to pool in the texture. To intensify color or for use on
dinnerware, apply a clear or matte clear glaze. For use on clay or greenware, apply underglaze, allow to dry,
and fire to cone 04. If desired, apply clear glaze and re-fire to cones 06-05 for earthenware and cone 5-10 for
stoneware (998°C–1285°C). For use on bisque, apply to cone 04 bisque, apply clear glaze if desired and re-fire
earthenware to cone 06/05 and cone 5-10 for stoneware. Generally, a clear glaze finish is applied to bring out
the true color and vividness of the product. We recommend S-2101 Clear for low-fire and SW-001 Stoneware Clear
Glaze unless noted SW-004 Zinc-Free Clear for mid-range.
One coat of Mayco Stroke & Coat® will create a translucent finish with subsequent coats adding
opacity. We suggest 2-3 coats for full opacity and all over coverage. Let dry between coats. Stroke & Coat®
glazes will fire to a gloss finish without clear glaze. However, if desired, a clear glaze (such as NT-CLR Clear
One Dipping Glaze or S-2101 Crystal Clear Brushing) can be added. For application on wet or leatherhard clay and
firing to cone 04, colors will retain their vibrancy with huge time savings. We recommend leaving an area
unglazed, such as the back or bottom of the unfired piece, to allow for out-gassing of the clay during the
single-firing process. Limit glazes to 2 coats including design work.
Crystal glazes were designed to mature at cone 06/05. Shake the jar well and stir during the application process.
Apply two to three even coats to shelf cone 04 bisque with a fan brush, allow to dry between coats. We recommend
a soft fan brush, such as CB-604 #4 or CB-618 #8 Soft Fan, for glaze application. Stir frequently as crystals
tend to settle in the jar due to their weight. Re-distribution of crystals may be required during the final
coat. Where you see the crystal is where you will see it bloom. Avoid heavy application of crystals at the
bottom of ware as the crystals bloom and can adhere to the kiln shelves or stilts. The crystals in the glaze
will melt when fired, which may create a textured surface. Jungle Gems™ Crystal Glazes have a natural
crazing that occurs when the crystals “bloom”. As that surface may be difficult to properly clean if
in contact with food, we recommend crystal glazes to be used on decorative ware.
Jungle Gems™ Crystal Glazes have been formulated to mature at cone 06/05. However can be fired at higher
temperatures. Their performance at cone 6 is noted on each individual product label. Crystals tend to flow at
higher temperatures so take care on vertical pieces. We recommend testing on your clay body and in your kiln
prior to use.
Shake for 5-6 seconds before use. Dispense glaze onto a palette (tile, plate, etc.) and apply with your brush or
decorating accessory of choice (sponge, stamp, etc.). Foundations® glazes were designed to mature at a shelf
cone 06/05. Apply 2-3 coats, on cone 04 bisque, allowing surface to dry in-between coats. Foundations® dries
quickly and speeds up your ability to handle or perform additional decorating. Glaze fires to high-gloss
finishes (excludes mattes), therefore does not need to be clear glazed. When applying to a large surface, we
recommend a broad, soft brush such as CB-604 #4 Soft Fan. Try to get the brush fully saturated (loaded) and
apply each coat in the same direction to minimize brush marks.
Foundations® have been formulated to mature at cone 06/05. However most will maintain their color at higher
temperatures. Their performance at cone 6 is noted on each individual product label. We recommend testing on
your clay body and in your kiln prior to use.
Shake for five to six seconds before use. Dispense glaze onto a palette (tile, plate, etc.) and apply
with a soft brush or decorating accessory of choice (sponge, stamp, etc.). Dipping your brush directly into the
jar may contaminate the jar’s contents, especially if you are using other glazes. Apply three to four coats to
your piece. Elements™ glazes were designed to mature at a shelf cone 06 (999° C or 1830º F). When applying them
over a large surface area, we recommend a broad, soft fan brush.
Moisten the brush with water first. The brush fully saturated (loaded) and each coat applied in the same
direction. When the wet look has gone from the first coat, you may apply the next coat of glaze. Be sure the
glaze has dried thoroughly prior to firing. A medium ramp/firing rate is recommended (250°F per hour) at shelf
cone 06. Elements™ can be fired at higher temperatures but will change in appearance. We recommend testing prior
to 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.
Dry mix products: Always wear a
NIOSH-approved respirator when handling dry glazes. Gently tumble
unopened bag to redistribute material, Sieving is not necessary. Mix one 10Ib bag of Dry material into
at least 10 pints of water. Stir thoroughly. Add additional water until desired Specific Gravity is
reached. Specific Gravity preference will vary between studios, persons, and practice. Our recommended
Specific Gravity is in the range of 1.47-1.51. This is for a 1 second dip time; you may want to mix to a
lower Specific Gravity if you layer your glazes or tend to dip longer. Stir well before each use. We
suggest using dipping tongs. Immerse the ware for 1-2 seconds. 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 distnbute the crystals; avoid heavy
crystal loading on the bottom 1/3 of your piece. Fire to preferred temperature, cones 5-10
(2167°F-2345°F / 1186°C-1285°C). Testing recommended. The choice of clay body, the thickness of glaze
application, the firing process, and temperature will affect the fired results.
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.
Safety Information Mayco Dinnerware Safety Information
FOOD SAFE VS. DINNERWARE SAFE VS. NOT SUITABLE FOR DINNERWARE DUE TO SURFACE CHARACTERISTICS
The Food and Drug Administration (FDA) issues a series of Compliance Policy Guides (CPG) that explain policy on regulatory issues related to the FDA laws or regulations, primarily “Food Safe”. Specific to ceramic products and supplies:
CPG Sec. 545.400 Pottery (Ceramics); Import and Domestic – Cadmium Contamination: delineates the acceptable test methods and levels of cadmium leach that is permissible
CPG Sec. 545.450 Pottery (Ceramics); Import and Domestic – Lead Contamination: delineates the acceptable test methods and levels of lead leach that is permissible
Please note: it is NOT illegal for a foodware item to contain traces of lead or cadmium as long as these substances test below the thresholds established in these guidelines.
“Food safe” seems to be one of the most confusing concepts for ceramic studios. It can be used differently among manufacturers, which lends to the confusion. There are some dissimilarities in how we ceramic manufacturers use definitions of food safe, dinnerware safe and other safety related information. Following is Mayco’s approach:
