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. |
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.
