Glass/porcelain paint pen, red, glitter, line width 2-4 mm, semi-opaque, 1 pc. Semi-covering water-based felt-tip pen with glitter - for glass, porcelain, metal - drying time: 4 hours, then cure at 160°C for 30 min. in a (not preheated) normal oven. Paint is then dishwasher safe. Shake the marker vigorously before use and then press gently on the tip a few times to allow the paint to flow. The marker is now ready for use. Use the marker on a clean, grease-free surface such as glass or porcelain. You can paint in all the colours of the rainbow, copy beloved cartoon characters or write a quote in a special calligraphy. If you are working on round vertical surfaces, it is helpful to first pre-draw the contours with a contour marker for glass/porcelain so that the motif colour does not run. Leave your work to dry for 4 hours. Then place it in a preheated oven (not hot air or steam) and cure at 160°C for 90 minutes - it's best to let it cool a little in the oven before letting it cool completely on a cooling rack. If you don't want other people to use your favourite mug, just write your name on it - an idea for all the mugs in the family! 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 cycle after the paint has hardened. Use the marker on mugs, tealight pots, lanterns, plates, bowls etc. made of glass or porcelain on which knives are not used to cut. The marker has the environmental label A - its colours are environmentally friendly and contain no ingredients that are harmful to adults or children.
