• Resumen

  • The relationships between chemistry, crime, and art are explored in an outreach activity for middle and high school students that investigates a possible art fraud. Students characterize pigment samples via spectroscopy and chemical analysis to determine whether the pigments in a questioned painting are consistent with those used by the alleged artist or are suggestive of a more modern origin. In lieu of actual paint samples, water-soluble dyes and metal salts are used as mock pigments, allowing characterization of colored solutions via UV–visible absorbance spectroscopy. Chemical tests for iron and copper further assist with pigment identification.
