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.
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: Amber Topaz provides a translucent, light honey-blonde color. 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 a transparent brown. 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 amber color but at three coats you will still obtain a translucent fired surface. Three+ coats will produce more opacity and less translucency. Heavy application may increase the incidence of crazing.
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: Turquoise provides translucent, bluish-green 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 fades. 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 turquoise color but at three coats you will still obtain a translucent fired surface. Three+ coats will produce more opacity and less translucency.
Cone 6: Leather is a matte brown glaze that displays shades of blue and green. The variation of the glaze is dependent on application. The thicker the application, the more homogenous the color will be. The glaze will break translucent where thinner and pool darker around surface textures.
Cone 10: Glossy blue becomes more prominent.
Cone 6: Amber Quartz is a warm amber matte glaze that adds accents of tan and brown. The variation of the glaze is dependent on application. The thicker the application, the more homogenous the color will be. The glaze will break translucent where thinner and pool darker around surface textures. Cone 10: Glossy purple/blue is more prominent.
Cone 6: Macadamia is a creamy vanilla matte glaze that adds accents of gold. We recommend firing our matte glazes to cone 6 to produce a satin matte finish.
Cone 10: Color changes to a variegated gray/cream. Glossy blue becomes more prominent. Tip: The variation of the glaze is dependent on application; Thicker application will result in a more homogenous color. The glaze will break over texture and can pool a glossy blue.
Cone 6: Frosted Lemon is a semi-opaque gloss yellow glaze that displays shades of yellow and white. The variation of glaze depends on application. The thicker the application, the more homogenous the color will be. The glaze will break translucent where thinner and pool darker around surface textures. Cone 10: Color changes to a light pink/purple.
Cone 6: Sand & Sea is a semi-opaque gloss glaze that displays shades of light green and gold. The variation of glaze depends on application. The thicker the application, the more homogenous the color will be. The glaze will break translucent where thinner and pool darker around surface textures. Cone 10: Color changes to cream/gray/brown.
Cone 6: Norse Blue is a semi-opaque blue gloss glaze that displays shades of light blue and green. The variation of glaze depends on application. The thicker the application, the more homogenous the color will be. The glaze will break translucent where thinner and pool darker around surface textures. Cone 10: Color darkens.
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: Yellow Matte is a semi-opaque matte yellow glaze. Lighter coatings will allow body characteristics to appear through the glaze (especially on dark and speckled clay bodies).
Cone 10: Changes to a 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: Lemon Meringue is designed to produce a bright yellow to white variegation depending on application. One coat will produce a bright yellow matte finish with little white variegation. Subsequent coats build a white variegation, muting the yellow.
Cone 10: Off-white variation darkens. TIP: Thinned coats produce a bright yellow satin finish. Thick applications will increase white variegation. Brush stroke application is visible in finished results. We recommend applying coats on bisque in different directions (crosshatch). Although finish appears opaque, surface decoration can be easily seen through glaze.
Cone 6: Weathered Blue is designed to produce a blue to white variegation depending on application. One coat will produce a sky blue matte finish with little white variegation. Subsequent coats build a white variegation, muting the sky blue. Cone 10: Off-white variation darkens. TIP: Thinned coats produce a sky blue satin finish. Thick applications will increase white variegation. Brush stroke application is visible in finished results. We recommend applying coats on bisque in different directions (crosshatch). Although finish appear sopaque, surface decoration can be easily seen through glaze.
Cone 6: Wintergreen is a light-green, semi-opaque satin matte glaze at cone 6. Lighter coatings will allow body characteristics to appear through the glaze (especially on dark and speckled clay bodies). Use three coats to achieve the deepest opacity.
Cone 10: Changes to a transparent pale green gloss with matte crystal growth. TIP: This is a true matte glaze at cone 5, becomes satin at cone 6.
Cone 6: Birch is a creamy opaque off-white glaze that breaks brown. Cone 10: Cream color remains and brown undertones darken. TIP: The thinner the the application, the more amber the glaze will be. The thicker the application, the more white floating you will get.
Cone 6: Copper Float glaze is a rich and complex midrange glaze with hues varying from reds, to coppers to gun metal blacks. Predominate coloration is a dark rusty red. The surface is satin-matte when fired to cone 5 or 6. Cone 10: Finish flattens. Color changes to a warm brown with some copper mottling. TIP: One coat will produce dark, greenish tones, thicker coats will add greens. Thickest applications will result in metallic red hues.
Cone 6: Cordovan develops a deep, burgundy red color with a semi-gloss surface when fired to cone 5 or 6. Cordovan produces a brick or iron red on white and red midrange clay bodies. Cone 10: Color changes to a dark metallic gray with copper/black mottling. TIP: Two coats should be plenty to get deep red, opaque coverage; light glazers may need to add a third coat.
Cone 6: Olivine has rusts and several shades of green flow from this mobile gloss glaze. Lighter coats produce muted greens and browns, 3 coats can produce a beautiful metallic green, almost mirror-like, luster. Cone 10: Color flattens and warm undertones come through. TIP: The thinner the application, the more green the glaze will be. The thicker the application, the more brown the glaze will be. If the glaze is fired cooler, the deeper brown and less variation will appear. If too brown, put back in the kiln and fire again.
Cone 6: Smoke is an opaque grey-blue stoneware glaze with soft, subtle variegating hues. Application thickness strongly influences the fired color; surface texture will also produce variegation during the firing. Cone 10: Color changes to a variegated sage green with a glossy finish. TIP: One coat creates a blue-grey haze over a weathered brown; Two coats intensify the grey cast while Three coats intensify the overall grey-blue opaque finish. Brown breaks on raised surfaces on the body.
Cone 6: Northern Woods is a semi-transparent bluish-green glaze. Lighter applications will produce a light translucent green with brown hues. As additional coats are applied the green hues will deepen and develop a bluish tint. Very nice on white stoneware and porcelain. Cone 10: No Change TIP: This glaze breaks brown and when applied thin the color will be brown. Apply three heavy coats to get the deep green color.
Cone 6: Tiger’s Eye breaks from a glossy deep brownish-red to frothy amber depending on the application thickness. one to two coats will produce browns and reds; three to five coats will result in more glaze movement and color variation. While you’ll experience beautiful movement with Tiger’s Eye, the glaze will not run off your ware during a cone 6 oxidation firing.
Cone 10: Color darkens.
TIP: Thinner applications will produce darker browns and reds; heavier applications will lean towards an opaque, light brown finish. Butted against another glaze, Tiger’s Eye will gently merge with it – SW-104 Black Walnut is a nice complementary glaze to use.

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 6 oxidation: Capri Blue is a variegated blue glaze that breaks over texture.
Cone 10 reduction: Semi-gloss finish with variegated blue/green.
TIP: The lighter the application the greener the glaze. The thicker the application the bluer the glaze. If you like Green Tea and oyster combos, try Capri blue because those 3 glazes are in the same glaze family. Gloss finish.
Cone 6: Dunes is a semi-opaque off-white soft matte glaze that breaks over texture.
Cone 10: Color darkens to variegated gray.
TIP: The lighter the application, the more brown the glaze will appear. The thicker the glaze application, the lighter tan the color.
Cone 6: Alabaster is a semi-opaque white soft matte glaze that breaks over texture.
Cone 10: Color darkens to variegated light gray/purple.
TIP: When using this glaze, you will be able to pick up the characteristics of the clay body due to it’s white semi opaque finish. Combos really well with 2 coats of stroke and coat on top. It has a satin finish. If you like combos with Sea Salt, you will get similar results with Alabaster minus the crystals.
Cone 6 oxidation: Frost Blue is a mottled blue soft matte glaze that breaks a muted green/gray.
Cone 10 reduction: Semi-gloss finish with variegated blue/light blue. Can exhibit green hues.
TIP: Because of the chemical make up, this glaze can vary between a green and blue finish. It has a satin finish. If you like the results that Robins Egg (SW116) gives you, then you will enjoy this glaze because they are made up of similar things.

Series Information: Mayco Stoneware Information & Brochure
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.
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.

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:
VIDEO
ICONS
AP SEAL
The AP (Approved Product) Seal identifies art materials are certified in a toxicological evaluation by a medical expert to contain no materials in sufficient quantities to be toxic or injurious to humans, including children, or to cause acute or chronic health problems as a wet glaze. Such products are certified by ACMI to be labeled in accordance with the chronic hazard labeling standard, ASTM D 4236, and the U. S. Labeling of Hazardous Art Materials Act (LHAMA).
CL SEAL
The CL (Cautionary Labeling) Seal identifies products that are certified to be properly labeled in a program of toxicological evaluation by a medical expert for any known health risks and with information on the safe and proper use of these materials as a wet glaze. CL products are NOT suitable for children 12 and under.
NON-TOXIC
Products bearing the Certified Non-Toxic seal have been reviewed by a toxicologist & deemed to have no health risk associated with the proper use of the product.
FOOD SAFE
Products bearing the Food Safe icon have been regulation and defined by the Compliance Policy Guide, maintained by the FDA. We have conducted testing on the individual glaze (or similar in formulation), which has passed standards for food safety when used according manufacturer’s direction.
DINNERWARE SAFE
Glazes identified with the Dinnerware Safe icon indicate the fired surface meets the FDA guidelines for food safe and is suitable for use on dinnerware.
NOT DINNERWARE SAFE
Glazes identified with this version of the Dinnerware Safe icon indicate the fired surface is NOT safe for use on dinnerware.
DINNERWARE SAFE WITH CLEAR GLAZE
Glazes identified with this version of the Dinnerware Safe icon indicate the fired surface is safe for use on dinnerware after a clear glaze or other dinnerware safe glaze is applied and fired.
