In 1967, the Artists Material Center at Carnegie Mellon University in Pittsburgh examined several of the "Vermeers" in their collection, under the direction of Robert Feller and Bernard Keisch. The examination confirmed that several of their paintings were in fact created using materials invented in the 20th century. They concluded that the "Vermeers" in their possession were modern and could thus be Van Meegeren forgeries. This confirmed the findings of the 1946 Coremans commission, and refuted the claims made by M. Jean Decoen. The test results obtained by the Carnegie Mellon team are summarized below.
