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. Once baked, it has the appearance of 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 paint adheres well to acrylic glass, mirrors, and many plastics. Without baking, the paint can be removed with water. The surface must be clean, grease-free, and smooth. A paint thinner should be used to dilute the color, allowing for beautiful watercolor effects.
