Glass/Porcelain Paint Marker, violet, glitter, line thickness 2-4 mm, semi-opaque. This semi-opaque felt-tip pen is water-based and features glitter, making it suitable for glass, porcelain, and metal. Drying time is 4 hours, followed by hardening in a (non-preheated) conventional oven at 160°C for 30 minutes. Once cured, the color becomes dishwasher-safe. Shake the marker vigorously before use and press the tip gently several times to allow the color to flow. The marker is now ready for use. Apply the marker on a clean, grease-free surface such as glass or porcelain. You can paint in all the colors of the rainbow, replicate beloved cartoon characters, or write a quote in beautiful handwriting. When working on round vertical surfaces, it is helpful to first outline with a contour marker for glass/porcelain to prevent the motif color from bleeding. Allow your work to dry for 4 hours. Then place it in the preheated oven (not convection or steam) and cure for 90 minutes at 160°C – it’s best to let it cool slightly in the oven before transferring it to a wire rack to cool completely. If you don’t want others to use your favorite mug, simply write your name on it – a great idea for all family mugs! The felt tip of the Mucki marker also makes it easy for children to write and draw with. The marker is ideal because it can be cleaned in the dishwasher on a low gentle cycle after the color has cured. Use the marker on mugs, tealight holders, lanterns, plates, bowls, etc., made of glass or porcelain, where cutting with knives is not involved. The marker has the environmental label A – its colors are eco-friendly and contain no harmful substances for adults or children.
