Watch an episode of “Antiques Roadshow” and you’ll likely hear “craquelure” mentioned by the art appraisers. This French term describes the pattern of fine cracks seen in the paint or varnish on a piece of art. The specific type of pattern can help pinpoint the exact age, type of paint used, and other factors about the piece. These clues help appraisers determine if what they are examining is a priceless masterpiece, or a reproduction found in someone’s attic.
