When turned on their side, these samples reveal a cross-section of the paint’s thickness, with each stripe of color representing a layer of paint, progressing from bottom to top in the order in which they were applied. In a cross-section sample of the leftmost figure’s elbow (swipe for a closer look), you see Renoir re-painting the flesh tone three times. Each of the white bands is a layer of opaque, lead-based pigment that Renoir used to cover the paint below in order to start again, either altering the position of the arm or re-working the color. Renoir’s layering process varies significantly in each sampled area of the painting. This inconsistency creates uneven thickness and rigidity throughout the paint layers that resulted in cracking—a condition issue that we’ll be discussing in a later post. #RenoirConservation #ImpressionistsEye #BehindTheScenes • Kristin Patterson, The Joan and John Thalheimer Associate Conservator of Paintings, taking a cross-section sample with a stereomicroscope.
