Cone 6 oxidation: Sparkle Black Engobe fires matte black with metallic specks. Specks may produce texture. Highly stable.

Cone 10 reduction: No change to base color. Specks bloom and become matte. Remains stable.

Tips:

• To enhance the sparkle and improve texture, use your fingers to burnish/polish the surface of the ware before the last layer is dry. Polishing is not needed when used in combination.
• Can be applied to wet clay, greenware or soft fired, cone 04 bisque.
• Engobes are often used for a variety of decorative techniques, such as sgraffito and majolica.
• Fires matte. Apply clear glaze (SW004) Zinc-Free Clear to intensify color or for use on dinnerware. 
• SW004 Zinc-Free Clear is recommended for a black finish. SW001 Stoneware Clear will change the color to a rich brown and affect the sparkle.
• Engobes will impact glaze results when used as a base. Engobes are used to change the color of your clay color surface without cross contamination and easy clean up in your studio. 
• Can be used in oxidation or reduction firings. Results may vary.
• The choice of clay body, thickness of application, firing process, and temperature will greatly affect the fired results. Always test your application on your clay body in your kiln environment.
