Picking Pigments is just what it sounds like, it’s an archive of pigments collected from 10 organic and synthetic objects. The technique used for this project is called chromatography - a process for separating components of a mixture.

The mixture cosists of a solvent, either acetone or 96% alcohol and dusks or chips of the original object.
When the mixture is ready, a strip of a filter paper is fitted into the cup of the mixture. Then , the pigments travel upwards, creating a chromatograph.The chromatography paper is made of cellulose, a polar substance, and the compounds within the mixture travel further if they are less polar. More polar substances bond with the cellulose paper more quickly, and therefore do not travel as far.
