Overglazes should be allowed to dry 24 hours before firing.
An overglaze marbleizer is a special effect product that is used with other metallic and lustre overglazes. It is applied over other products and when fired produces a star burst, spider web effect.
You cannot apply marbleizer to an overglazed piece until the other overglazes are completely dry.
Overglaze refers to the group of colours which are applied to a previously glazed and fired surface.
