Abstract Expressionism – especially Pollock, not the more academic painters like De Kooning – made the threshold between illusion and the stuff of painting lower, the distance between them closer. Pollock made all things about the picture, all the stuff, actual. Taking the canvas off the stretcher, putting it on the floor, made it more real. Mixing up different kinds of paint, getting it to stain in, was getting at a kind of materiality.
