Beginning in the 1930’s many artists began experimenting with synthetic paint, including household paint. When Jackson Pollock employed his “drip” technique in the 1950’s he used a mixed media of traditional oil paint, house paint and sometimes an acrylic. Since the 1970’s a number of his most valuable works have required extensive restoration because much of the paints he used deteriorate in a short time.

Oddly enough, Leonardo had the same problems!
