Crazing is an effect created in paint when the upper layers dry, and shrink faster than the lower layers. This causes the upper layers to split apart. This is usually not a desired effect in oil paint as it can effect the structural integrity of the painting. It can be desirable in acrylic paint as unique effects can be achieved. Some of the effects include layering colors over top of one another. Golden’s crackle can be used to enhance the effects. There are also mediums like Golden GAC 800 and Liquitex pouring medium that prevent the effect from happening by making the paint dry more evenly. An artist that is well known for using crazing effects is one of the New New Painters, Graham Peacock.
