Before painting with Vitrea 160, simply degrease with alcohol or soapy water. Allow to air dry for 24 hours once painted, then bake in an ordinary domestic oven. Simply place the decorated object in a cold oven. Once the temperature has reached 160°C (325°F), allow to bake for 40 minutes. After baking, colours are dishwasher safe and resistant to detergents and common solvents.
