      Coyote Glaze Application instructions

      Basic Glazing Instructions
      First you want to apply wax resist to the foot of your pot (where you don't want any glaze). When you dip your pot in bucket of glaze, the glaze won't stick where you have waxed. The glazes become molten glass in the kiln, so if there is any glaze on the bottom, your pot will stick to the shelf. This will wreck your pot and your kiln shelves! Paint a thin coat of wax on the bottom, as well as up the sides at least ¼ inch. All glazes move a little in the firing, and some are quite runny. Always leave enough room for your glaze to flow some without sticking to the kiln shelf. Until you are familiar with a particular glaze, it is better to leave some extra room.

      • Use a thin coat of wax. It works better and dries faster.
      • Let the wax dry for at least 15 or 20 minutes before dipping a pot in glaze.
      • Use an old cruddy brush, they are never the same after using for wax.
      • Clean your wax brush in warm water with a drop or two of dishwashing soap.
      • Be careful not to get the wax where you don't want it, i.e. waxy fingerprints.
      • Before you glaze your work, you should quickly rinse it under cold water.
      • Thoroughly mix the glaze just before you use it.

      Dipping
      To coat the whole piece in a single glaze, the easiest technique is to pick it up with a pair of glaze tongs, dip it in, count to three and pull it out. Make sure to empty it as you withdraw it. If you pull a bowl out still full of glaze it will weigh so much that the tongs will break through. Hold it upside down over the bucket to drain the excess glaze. There will probably be some glaze sticking to the waxed areas; wipe off what you can while you are holding it with the tongs. Set the piece down and let it dry. After it is dry enough to handle, turn it over and sponge off any glaze still remaining on the bottom. The foot must be perfectly clean before it can go in a kiln.

      Brushing
      For brushing, most glazes need 2 to 3 coats. It is easier to get even coverage if you brush the first coat side to side, then the next coat up and down.

      Firing
      These glazes work best when fired between cone 5 and 6 (Orton Standard or Self-Supporting Cones, used as a witness cone placed on the kiln shelf during firing). If you use a kiln sitter you usually have to use a cone six in the sitter to achieve a good cone 5. For automatic kilns, we fire to cone 5 (fast) with a 15 minute hold. Every kiln is different, so you may have to fine tune your firing to achieve the best results.

      Texas Two-Steps

      Oil spot glazes at cone 10 have provided some of the most striking and unique finishes in ceramics.  Now, Coyote Texas Two Step glazes provide the same sought-after effect at cone 6, in a breathtaking variety of color combinations.  These glazes work as a two part system, with the top coat pulling away to reveal brilliant spots of the glaze beneath.


      To use the Texas Two Step glazes, simply apply a Step One Undercoat to bisque ware (two or three coats brushing, one coat dipped) and wait for it to dry completely. Then, cover all or part of the first color with a Step Two Overcoat. When the piece is fired to cone 6 in an electric kiln, the glazes will interact, creating a phenomenal oil spot effect. Varying the thickness of the glazes during application will have a dramatic effect on the finished piece, as the thicker the glazes get, the larger the spots they create will be. We found the optimum thickness to be two coats of the Step One Undercoat and three coats of Step Two Overcoat, but you may prefer thicker or thinner applications for different effects. Try experimenting!

      Spots become noticeably larger and less regular after each new coat of glaze. You will need at least one Step One Undercoat and one Step Two Overcoat, used together, to get the oil spot effects.

      Below is the complete Two-Step series, with every overcoat/undercoat combination shown.  To use the Texas Two Step glazes, simply apply a Step One Undercoat to bisque ware (two or three coats brushing, one coat dipped) and wait for it to dry completely. Then, cover all or part of the first color with a Step Two Overcoat.  When the piece is fired to cone 6 in an electric kiln, the glazes will interact, creating a phenomenal oil spot effect. Varying the thickness of the glazes during application will have a dramatic effect on the finished piece, as the thicker the glazes get, the larger the spots they create will be.  We found the optimum thickness to be two coats of the Step One Undercoat and three coats of Step Two Overcoat, but you may prefer thicker or thinner applications for different effects.

      Coyote Glaze Safety Info & SDS

      Row content

      Coyote Glazes are evaluated by an independent toxicologist.  None of their recipes use lead and all are non-toxic in the liquid state.  Continue reading below for more information.

      Liquid Glaze
      Click Here for Liquid Glaze SDS
      All Coyote liquid glazes are non-toxic under proposed use conditions (brushing, pouring, and dipping). All Coyote glazes are lead free, most are cadmium free; however none of these glazes should be taken internally as they contain ingredients not suitable for ingestion or inhalation. All Coyote glazes contain quartz (silica), and some contain cobalt, chromium and cadmium. We do not recommend that the glazes be used for spraying, as that would increase the risk of inhalation.

      Product labeling; All Coyote glazes have been evaluated by an independent toxicologist and are properly labeled in accordance with ASTM D-4236. In liquid form none require any warning statement other than "conforms to ASTM D-4236." However, we voluntarily adhere to stricter labeling guidelines which include the following statements:
      -WARNING: This glaze contains quartz, and might contain titanium dioxide, chromium, cobalt, or cadmium.
      Possible cancer agent based on tests with laboratory animals, exposure may cause lung damage.
      -Keep out of reach of children, avoid inhalation. Call your local poison control center for more health information. 
      -This product contains chemicals known to the State of California to cause cancer or birth defects or other reproductive harm.
       
      Dry Glaze
      Click Here for Dry Glaze SDS
      Coyote Dry Glazes contain the same ingredients as the Liquid Glazes. However, due to the increased potential risk of inhalation, they are not labeled as non-toxic. Liquid glaze or underglaze when sprayed also poses an inhalation risk.  All Coyote glazes contain quartz (silica), and some contain cobalt, chromium and cadmium. Avoid creating dust, use a NIOSH approved respirator and local exhaust. All of our glazes are lead free, most are cadmium free; however none of these glazes should be taken internally as they contain ingredients not suitable for ingestion or inhalation.

      Product labeling; All Coyote glazes have been evaluated by an independent toxicologist and are properly labeled in accordance with ASTM D-4236. Dry glazes have the following statements:
      -WARNING. This glaze contains QUARTZ (SILICA) POSSIBLE CANCER AGENT BASED ON TESTS WITH LABORATORY ANIMALS. EXPOSURE MAY CAUSE LUNG DAMAGE KEEP OUT OF REACH OF CHILDREN AVOID INHALATION CALL YOUR LOCAL POISON CONTROL CENTER FOR MORE HEALTH INFORMATION.
      -WARNING: This product contains crystalline silica and/or other chemicals known to the State of California to cause cancer. MSDS Available. Conforms to ASTM D 4236
      Food Safety
      Currently the only materials that are regulated by the FDA regarding food safety in ceramic glazes are lead and cadmium. All Coyote glazes are lead free, and those containing cadmium (in the form of inclusion stains) have in our testing passed FDA cadmium release guidelines when properly fired. 

      Because of the many variables in every studio, we cannot guarantee that your ware will be safe for food use.  Firing temperature, interaction between different glazes or underglazes, or possible contamination can all affect the food safety of your work. Potters making ware for food use must test their own work to determine its dinnerware status. We recommend that ware produced for sale be tested by the potter at an approved laboratory before it is marketed. You can find information about the lab Coyote uses at www.vanguardglobalassociates.com (Vanguard Global Associates).

      Amethyst, Brick Red, Buttercup, Butterscotch Shino, Cedar Shino, Cherry Satin, Clementine, Coral Satin, Dragon's Eye, Dusty Rose, Enchanted Sunset, Fairy Rose, Fire Opal, Lemon Cream Satin, Mulberry, Orange, Passion Red, Peach Blush, Persimmon, Phoenix Egg, Plum Shino, Pomegranate, Pumpkin, Really Red, Red, Red Orange, Rhubarb, Sedona Sunset, Sundrop, Sunrise Shino, Sunset Pink, Sunshine Yellow, Tangerine, Tiger Lily, Texas Rose, and Turquoise Lake contain Cadmium in the form of inclusion stains; in our testing, all of these glazes passed FDA guidelines in leaching tests for cadmium release.

      Blue Matt, Bronze Temmoku, Crystal Aurora, Crystal Celadon, Crystal Nebula, Crystal Lagoon, Green Matt, Green Shino, Iron Matt, Ivory Crystal, Peacock Green, Rose Crystal and Turquoise Matt are not recommended for food use, as they may change color or texture with repeated exposure to food and dishwasher detergents. 

      The Crawl glazes are not recommended for food use due to their texture.
       
      California Prop 65 Warning
       California law now requires that certain warnings must be prominently displayed on the website and labeling of any product containing materials from their list of regulated chemicals. To comply with this, all Coyote Glazes and Underglazes now have some variation of the following warning:

      WARNING: This product can expose you to chemicals including Quartz and Lithium Carbonate, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov
      Coyote Dry Glaze Information and Mixing Instructions
      Coyote Glazes are available dry for your convenience, in 5, 10, or 25 lbs. bags.  Dry glazes contain the same ingredients as the wet glazes (minus the water) and can be used to brush, pour, dip, or spray.
      Click Here for Dry Glaze MSDS
      Quick Facts
        • 5 Lbs. of dry glaze needs approximately half a gallon of water (every glaze is different, check the label) and will yield about three quarts of glaze.

        • 10 Lbs. of dry glaze needs approximately one gallon of water and will yield about a gallon and a half of glaze.

        • 25 Lbs. of dry glaze needs approximately two and a half gallons of water and will yield between three and four gallons of glaze.

      • When mixed with water, Coyote dry glazes are suitable for brushing, pouring or dipping, and do not require the addition of any suspension or brushing ingredients; if they need it, it's already in there.
      Quick Mixing Instructions
        • Wear an appropriate respirator and gloves, and use adequate ventilation when mixing.

        • Measure the amount of water recommended on the label (or just a bit less) into a clean bucket.

        • Slowly add the dry glaze while stirring continuously. Scrape the sides and bottom of the bucket and mix thoroughly.

        • Screen through a 60 mesh sieve.

      • Dip and fire a test piece; if too thick, add a small amount of water and retest.
      Tips and Troubleshooting
      Because most of our dry glazes include CMC and bentonite they may take a little longer to dry than you are used to with dipping glazes, but they dip very well, stay suspended in the bucket and can also used for brushing. At Coyote Clay School & Studios we dip everything, with excellent results.

      Don't be tempted to add more water than is suggested on the label without testing! Every glaze is different, and each label has a suggested water content for that glaze. Some of our glazes will be quite thick when mixed according to the instructions on the label. Glazes that work best with a thicker application will be thicker in the bucket, and glazes that work well with a thinner application will be thinner.

      Some of our glazes, especially the Mottled Glaze series, gel when left undisturbed. Mix them vigorously and they will thin out with no additional water. We highly recommend a drill with a mixing attachment for mixing glazes.

      There are a lot of variables in how much glaze ends up on a dipped piece, so mix up your glaze, then dip and fire a test piece! You may find that you prefer your glaze a little thicker or thinner than we do. By keeping accurate records of how much water you use, you can reproduce your preferred glaze thickness well.

      Because hydrometers are misleading when measuring thick materials, here at Coyote we determine specific gravity by weighing a particular volume of glaze. If you want to reproduce exactly the consistency of our liquid glazes as we sell them, you will need a 500 milliliter flask and an accurate scale.

      To measure the specific gravity of a glaze: Tare (subtract) the weight of your flask from the scale. Fill the flask exactly to the 500 ml mark with glaze and weigh it. If your glaze is heavier than the target weight, add water and re-weigh.
