Tips & Techniques


1. Cover-Coat colors may be tinted using E-Z Strokes™ or other Cover-Coat colors to create unique custom hues.

2. To create carved designs, a.k.a. sgraffito, gently scratch through the applied color to reveal the color or the clay body beneath it.

3. Painting with Cover-Coat Underglazes is similar to painting with acrylic paints and is a great fired alternative for a tole and decorative painter. Colors are opaque and generally one color covers the one beneath it. They must be fired to ensure maturation and stability. Clear glazes over all shows the truest colors.

4. Cover-Coat Underglazes are perfect for airbrushing and brushwork.

5. Great for layering because they dry quickly and can be painted over without lifting the colors underneath.
