Studying physical evidence on the surface of “The Great Bathers” gives clues to the order in which Renoir worked, which areas he re-painted, and which were less altered. Scanning the painting with a Crono Scanning XRF spectrometer allowed us to create maps of the location of elements used throughout the painting, which signify the location of different pigments. Not only can this help us understand Renoir’s painting process, it can also help to confirm areas of prior restoration. (Swipe left) In this map of elements within the central figure, red designates the element iron, showing areas that are likely natural earth pigments that were a common component of Renoir’s palette. Green shows the element titanium, which wasn’t used in artist’s materials until 1921, proving that these areas are later restorations. Follow along as we reveal new insights from the process of researching, analyzing, and conserving Renoir’s “The Great Bathers,” now on view in The #ImpressionistsEye. #RenoirConservation #BehindTheScenes • “The Great Bathers,” 1884–87, by Pierre-Auguste Renoir, capturing data with a Bruker Crono Scanning XRF spectrometer.
