The KREUL Glass & Porcelain "Clear" dries transparent, crystal clear, and glossy. It can be applied to porcelain, glass, ceramics, terracotta, and metal. After drying (approximately 4 hours), the color can be baked at 160 °C for 90 minutes. After this process, it has an appearance similar to colored glass and is water- and dishwasher-safe. When painting, care should be taken not to paint surfaces that come into contact with food. Additionally, the color adheres well to acrylic glass, mirrors, and many plastics. Without baking, the color can be removed with water. The surface must be clean, grease-free, and smooth. To thin the paint, a paint thinner should be used to achieve beautiful watercolor effects.
