Picasso the decorator?

Picasso was undoubtedly a truly great artist. Recent work using the X-ray fluorescence nanoprobe at Argonne National Laboratory has added weight to the notion that Picasso was one of the first master painters to use common fast drying enamel house paint rather than traditional artists' paint. By comparing decades-old paint samples purchased on e-Bay with samples from Picasso paintings, scientists were able to show that the chemical makeup of paint used by Picasso matched that of the first commercial house paint, Ripolin. The purity of the zinc oxide and the lack of impurities such as Pb and Fe were important pointers.
