David Alfaro Siqueiros called one of his techniques accidente controlado, the controlled accident. Nitrocellulose lacquers, “también llamadas piroxilinas” (also called pyroxylins), played a central part in it. They were used for car paint and nail varnish. He threw the paint with a brocha de aire, an air brush. Jackson Pollock attended an experimental workshop held in New York.
In 2015, a UNAM team led by Roberto Zenit explained the physics behind the technique, a fluid phenomenon called the Rayleigh-Taylor instability.
