Renoir is one of those art historical giants that I\u2019m sometimes guilty of overlooking, simply because of how frequently his imagery appears in contemporary culture. An upcoming treatment of a Renoir painting at work, though, meant that it was high time to take a closer look. Fortunately, Kelly Keegan of the Art Institute of Chicago gave a fantastic presentation on \u201cRediscovering Renoir\u201d at the 2015 AIC conference, which was brimming with details about the artist\u2019s materials and techniques, and beautiful photomicrographs and graphics.
\nThe presentation was a summary of findings from the in-depth technical study of Renoir’s 15 paintings at the Art Institute of Chicago, conducted as part of the\u00a0<\/span>Online Scholarly Catalog Initiative<\/a>. Examination techniques included x-radiography; infrared, transmitted light, and ultraviolet imaging; x-ray fluorescence spectroscopy; scanning electron microscopy\/energy dispersive x-ray spectroscopy; polarized light microscopy, surface-enhanced Raman spectroscopy; thread counting; and, of course, lots and lots of looking under the microscope.
\nRenoir was both less and more methodical than I expected. For example of the former, he didn\u2019t have a reliable art supply merchant. His canvases ranged in fineness, and thread counting demonstrated that they never came from the same bolt of cloth. Although most of the paintings are now lined and on non-original stretchers, seven canvas stamps from four different suppliers were found. His ground layers were usually white or off-white, with dragged inclusions and palette knife marks indicating application by the artist. The use of the palette knife often exposed the tops of the canvas weave.
\nRenoir\u2019s compositional planning shows his meticulous side. Even the highly impressionistic work Chrysanthemums<\/i> includes a graphite underdrawing<\/a> with individual petals. The artist varied his preparatory drawing medium, using dry media, blue or brown paint, or red lake washes. Slight adjustments were common, and a dramatic change was discovered in Lunch at the Restaurant Fournaise, <\/span><\/i>the catalog cover image: an isolated two-person encounter<\/a> was initially depicted, but the final product has three figures. Later in Renoir\u2019s career, infrared examination shows the debilitating effect that rheumatoid arthritis had on his once-confident draftsman\u2019s hand.

\nRenoir\u2019s color palette included vivid pigments, including emerald green, cobalt blue, various bright yellows (see image above), vermilion, and red lakes, in addition to iron oxides. One color he considered an \u201cunnecessary purchase\u201d was yellow ochre, which he ironically preferred to mix himself using much more expensive pigments. Although he did a lot of blending on the painting, he kept his brush clean to prevent muddying of the colors. In contrast to most other Impressionists, Renoir’s paint layers are quite thin relative to the ground layer. The influence of his teenage training as a porcelain painter is evident in his use of thin glazes, especially with luminescent red lakes over white ground. He used a palette knife at times to scrape away layers and create texture in the interstices of the canvas weave.
\nThis presentation was chock full of technical information and interesting quirks about Renoir that not only make me feel more prepared to approach a Renoir treatment, but also give me a much better appreciation for an artist that deserves a close look. His work shines under the microscope and when considering the individual behind the paintings. The Online Scholarly Catalogs are a wonderful resource, and I\u2019m grateful to have gotten Keegan\u2019s dynamic overview\u00a0of the Renoir content.<\/p>\n","protected":false},"excerpt":{"rendered":"
