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.
If you want to use a sponge to apply an overglaze, allow the lustre or metallic to thicken slightly by exposing a small amount to the air and allowing a little evaporation. The thickened material will hold the sponge pattern after application
All overglazes should be allowed to dry for at least 24 hours before firing.
