Metal Soaps in Oil Painting

Caption

NIST researchers collaborated with the National Gallery of Art and other organizations to study "metal soaps" found in oil paintings that can cause the painting to degrade over time. They used a multiscale approach involving various spectroscopy techniques to identify metal soaps in a sample from an oil painting by French artist, Jean-Baptiste-Camille Corot.
