Pablo Picasso, one of the most famous artists of the 20th century, had stumped art lovers for decades by using a mysterious kind of paint that hid brush strokes. Recently, scientists at the Argonne National Laboratory near Chicago analyzed Picasso's painting The Red Armchair (1931) and discovered that Picasso used regular house paint. Their close examination even discovered what brand of house paint Picasso used -- Ripolin, a common house paint available at the time.

Re: Picasso Used House Paint
One artist who used house paint exclusively was Jackson Pollock, once he developed his so-called drip paintings. He used cans of ordinary household enamel paint, into which he would dip his brushes, often just plain sticks and — would you believe — turkey basters, and he would then drip, and flick, and squirt the paint from above the horizontal surface of his canvas.
