The KREUL Glass & Porcelain "Classic-Metallic" dries opaque and smooth with a metallic shimmer. It can be applied to terracotta, glass, metal, and porcelain. After drying (approximately 4 hours), the color can be baked at 160 °C for 90 minutes. After this process, the appearance resembles glazed ceramics and is water- and dishwasher-safe. Additionally, the color adheres well to many plastics, acrylic glass, and mirrors. Without baking, the color can be removed with water. For thinning, a color thinner should be used that does not affect the adhesion properties. The paint is not food-safe, so areas that come into contact with food should be left unpainted.
