Diffusion Gradients, 2018

Energy and matter flow along gradients forming stars and eventually planets. On Earth, about 9 or 10 billion years later, chemical reactions in the primeval ocean were being driven by thermal and electrochemical gradients. The evolution of these gradients is the chemical evolution of life. I wanted to interact with these gradients, trace them, use them to look into my past as non-living matter. The images below were made by transferring stacks of exposed photographic paper between baths of photo developer, fix, stop, water and different combinations of these at different temperatures. The chemistry seeps between the sheets, doing work. There is a progress towards the center and a record of the path.
