Opaque, water-based marker suitable for both glass and porcelain. The decorated item is dishwasher safe at low temperatures after oven fixing. This marker adheres best to a clean, dry, and grease-free surface. Shake the marker well and gently press the tip up and down until the paint flows to the tip. Allow the decorated item to dry for 8 hours, then place it in a cold oven (not a convection or steam oven). Set the temperature to 230°C. The item will be fixed after 40 minutes. Turn off the oven and let the item cool in the oven.
