Grettel found that a question was        colour. She asked Nehemiah, a
            ringing in her ears throughout the       fellow pilgrim and Chemistry

            pilgrimage. She wondered how the         student and lecturer, if the chemical
            art of painting (if just a matter of     pollution could be extracted from

            using paint on board) could possibly     the river and made visible as a
            communicate any kind of impactful        colour. His answer was affirmative.

            message about the pollution of           Firstly, you can directly collect water
            water by invisible chemical              samples and then dry them out in

            pollutants and microplastics. As she     the chemical laboratory under a
            noted: “This made me feel more           slow heat. This leaves you with an
            deflated.” But she speaks of a           actual sediment, a “dust,” that you

            moment of inspiration in the             could mix into pigments. But
            afternoon of that second day. “That      secondly, heavy metal content in a

            afternoon there was a moment             fluid medium can be analysed

            when we were having a group              through the process of
            reflection alongside the Swartkops       chromatography, which represents
            river, and I thought, maybe this         metals through colour.  In other
            landscape should paint itself.” She      words, if you cannot collect enough

            decided that the way she could           actual pigment, you can use the

            connect painting (something              chemical analysis to provide you
            intrinsically visual) to invisible       with a pallet of colours with which

            chemical and plastic micro-pollution     to represent the invisible. Grettel
            was through its translation into         set out to do both.
