    Oil Paint

    Hello MITRA,

    On one of your resource handouts you say, "Some artists choose to place their paintings in direct sunlight for a certain period of time as UV light can break up some of the chemical bonds that are responsible for yellowing."  What length of time, more or less, is it suggested that an oil painting be exposed to sunlight to counteract yellowing?  Any caveats, besides being aware of fugitive pigments?

    ‚ÄčIt really depends on how "yellow" your painting is and (as you stated) the presence of any pigments that are fugitive. We do not recommend exposure to direct sunlight only indirect/diffuse and preferrably near or close to a window. We would advise checking on the painting one day at a time and to not continue to expose the surface any longer than is necessary.
