Semi-opaque paint markers, to be primed, water-based, for glass and porcelain. The decorated object can be washed in the dishwasher at a low temperature after being set in the oven. This marker adheres better on a clean, dry, and non-greasy surface. Shake the marker well and gently push the tip up and down until the ink flows to it. Let the decorated object dry for 8 hours, place it in a cold oven (not a convection or steam oven). Set the temperature to 230°C. The decoration will be set on the object after 40 minutes. Turn off the oven and let the object cool inside it. * Set of 12 colors.
