In these tests, I continue to explore the nature of water. The chemical properties of pure water are universal, and unchanging, and what gives natural water courses their identity, and influences what else can live in them, exists within water and between the spaces of its polar molecules. I’m seeking to reveal these defining elemental signatures. One of the most important of these is pH, that is whether the water is acidic or alkaline, and this can be measured by adding a pH indicator to the sample. The colour of the indicator changes according to the pH value of the water. I travelled 86 miles today and collected nine water samples on my journey and experimented on them.
Not unlike Damian Hirst’s spot paintings but the colours that are generated are predetermined by, and are a direct reflection of the natural world. Oh and there’s acid rain there in the mix too!
Hoping to develop this into a much larger project with the help of a pointillist
