Engobes are either natural clays or a mixture of clays and ceramic raw materials, and are typically rich earth colors and subdued tones. Only water is added to obtain a working consistency like thick cream. AMACO Engobes can be applied to unfired clay using a variety of methods; they may be brushed, poured, or trailed thinly on wet or dry greenware. Sometimes they are used to cover an inferior body, but generally are applied as decoration to contrast with the color of the clay piece. Slip painting, slip trailing, and Sgraffito are especially good decorating methods for engobes. For best results when slip painting, use short brush strokes. The designs should be compressed with direct strokes of the brush which is heavily loaded with the engobe. More elaborate designs may be made by the slip trailing method. Try decorating with a slip trailer to produce thin and thick line designs. When the Sgraffito process is used, designs are scratched into a layer of engobe so the color of the clay shows through.
AMACO Engobes have only been tested and approved as dinnerware safe when applied and fired under LG-10 Clear Glaze. They should not be used on surfaces which come in contact with food or drink if left unglazed. AMACO Clear Glaze LG-10 and HF-9 or any other dinnerware safe glaze is recommended to be used over AMACO Engobes to make them dinnerware safe.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
