Airbrushing nontoxic glazes


Important note: Nontoxic glazes are the ONLY glazes that Duncan recommends for spray application by hobbyists, students and participants in institutional ceramics programs.

Adequate ventilation is recommended when spraying any glaze.

If a commercial spray booth is not available, an improvised spray booth constructed of cardboard or other material can be used to catch the overspray.

The spray booth should be placed near an open window to ensure good ventilation.

Dinnerware-safe glazes


Most nontoxic glazes are safe for application to food and dink containers. The exceptions are nontoxic glazes which produce a textured or crackled surface. Food particles and bacteria can be trapped in these porous surfaces, creating unsanitary conditions.

Dinnerware-safe glazes are identified with the notation SAFE FOR FOOD CONTAINERS on the front of the label. If a glaze label does not contain this phrase, do not use the glaze on pieces that come into contact with food or drink.

Follow the directions on the jar label closely.

Do not mix dinnerware-safe glazes, as the balance of ingredients in each glaze will be disrupted. Each mixture would have to be retested by an approved laboratory to determine if the mixture is also dinnerware safe.

Proper firing of dinnerware-safe glazes is critical. Pyrometric cones should be used on the kiln shelves to ensure that the pieces are fired hot enough. Dinnerware-safe glazes should be fired to a mature witness cone 06.



The uniquely shaped Tulip® Capstand allows paint to be stored upside-down, minimizing air bubbles and improving flow for better application and control. Our Tulip 1.25-oz. EasyFlow bottle is specially designed to reduce hand fatigue, and improve accuracy and precision in application.

Medical supervision


Pregnant women who are active ceramists should notify their physician of their work with ceramic products.

Personal hygiene


It’s always a good idea to keep your snacking away from your crafting or painting ceramics. It’s too easy to grab a piece of bisque with salty fingers and stain the bisque so the glaze won’t cover the area. Oily fingers can also mark and stain your fabric surface.

Always protect any cuts or open wounds on your hands. Wash your hands and arms thoroughly afterward and be sure to put away materials where small children cannot reach them. And remember, whatever utensils you use in the crafts room should stay in the crafts room. You don’t want to double dip your utensils between crafts and food!

Read labels with care


Conforms to ASTM D-4236. Certified to contain no materials in sufficient quantities to be toxic or injurious to humans or to cause acute or chronic health problems.

Certified to be properly labeled with information on safe and proper handling and use. Have undergone toxicological evaluation by a medical expert. Labels disclose any known health risks associated with improper handling.

Shelf Life


Freeze-thaw and oven stability tests are conducted on our crafts products to ensure long shelf life, so you can be assured of the utmost quality.

Sprays, solvents and overglazes


These products are easy to use safely and will present no problems as long as these important rules are observed:

  1. Keep out of reach of children.
  2. Use in a well-ventilated area.
  3. Never smoke when spraying.
  4. Clean up after use.

Sprays, solvents and overglazes should not be used near a heat source or open flame, or close to the kiln. Do not smoke while spraying. Containers are to be kept closed when not in use. Rags and paper towels or tissues used with these products should be placed in the trash for immediate disposal.

Tulip Fashion Dyes


Always wear gloves when working with dyes. Dry dye powder can cause an allergic reaction in some people. Dye is permanent. You may not see the dry powder on your skin, but once it gets wet, it’s going to stay there awhile until it wears off.

Also avoid inhaling dye dust over an extended period of time. If you’re dying a bunch of T’s for a party or event, just make sure you’re getting air circulation in a well-ventilated area.

Remember to supervise children doing tie-dye projects. You want the dye on the fabric and not on your kids!

Wash Test


Our full line of dimensional and soft fabric paint, fabric dyes and fabric glues and adhesives undergo extensive wash tests to ensure consistent color quality and performance.

Work Area


Keeping your work area clean is always a good idea when working with crafts, and a must when working with ceramics.

  1. Use a damp sponge to wipe down work surfaces and shelves to eliminate dust.
  2. Work on newspaper or paper towels for easy cleanup.
  3. Clean up spills as you go.
  4. Wet-mop floors to control dust (sweeping spreads the dust).
  5. Wash brushes immediately after use so color doesn’t dry in the bristles.
  6. Clean jar rims before closing to avoid buildup of dried product.
  7. Keep dust under control.
  8. Did we mention dust? Dust often to keep work area clean!
