China paints belong to the overglaze family of colours.
If an area to be covered with china paints is large enough or does not have too many recessed areas, you may have better luck in applying colours with a pad.
A pad , as referred to in china painting, is a piece of china silk filled with either cotton or lamb's wool and tied together to form a loose ball.
Overglazes should be allowed to dry 24 hours before firing.
Overglaze refers to the group of colours which are applied to a previously glazed and fired surface.
