Layer it up and turn it out. This is the DIRTY pour. Watch and find out how to use Liquitex Basics color with our Pro Iridescent Pouring Medium to create the perfect pearly metallic pours. Mix your colors into the medium (around 5% color to 95% medium is good) in separate jars, then layer up in one pot, put your painting surface on top, turn them over and see it flow. This technique creates sublime puddles of poured color with fantasy blends you can then drag out with a fork, or tilt to move around the surface. Leave to dry to a super-stable, high lustre, iridescent finish.
