Ancient Paints Part 2: Lake Pigments

No votes have been submitted yet.
A lesson that dives into the fusion of Art and Chemistry. Students will make their own pigments using common plants by using an acid-base reaction. They will test the effects of different solvents in extracting pigments, and check their experiments for colorfastness. This lesson can be used in conjunction with two other lessons as part of a unit on making paint. If desired, this lesson can be a fun way to use stoichiometry and calculate pH.
