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