The KREUL Glass & Porcelain "Chalky" can be used on terracotta, glass, metal, and porcelain. It dries opaque and matte with a chalky appearance. After drying (approximately 4 hours), the color can be baked at 160 °C for 90 minutes. After this process, the painting becomes water- and dishwasher-safe as well as saliva-resistant. For thinning, a color thinner should be used that does not affect the adhesion. The paint is not food-safe, so areas that come into contact with food should be left unpainted. Additionally, the paint adheres well to many plastics, acrylic glass, and mirrors. Without baking, the paint can be removed with water.
