This article describes two experiments suitable for a first-year general chemistry laboratory program emphasising “everyday chemistry.” The first experiment is the synthesis of various inorganic pigments that have been used by artists painting in oils. The second treats such pigments as unknown samples in a semimicroanalysis scheme, allowing the goal to be a detection of forgery. Each experiment can be performed in a three-hour time period and can be conveniently tailored for a team or individual exercise.
