Cosmic Shimmer Crackle GlazeAn acrylic medium to produce consistent cracking of decorative paints. Simply choose two colours to layer on your project. Paint your base layer, then apply a layer of crackle glaze and apply your second chosen colour in right angles to your application of crackle glaze. The top layer will crackle as it dries to reveal your base coat underneath. Apply a thicker layer of crackle glaze for a more pronounced crackle effect.50mlPlease Note that most of the Cosmic Shimmer product is water-based and therefore could be affected by colder temperatures. This includes time in transit. Please take this into consideration when placing your order in the months of January and February.
