This clear glaze can be used as a topcoat to create a crackled eggshell pattern, in just one step. The glaze can be tinted with fluid acrylics and after it dries the cracks can be further enhanced by applying antiquing cream. Crackle results vary depending on thickness of application and technique used to apply the glaze. It can be used on cardstock, canvas, papier mache, wood and more. It is fast drying, acid-free, water-based and non-toxic.
