SINK, a Shell Dissolving Objet d’art

By Daniel de la Calle

Artist Julian Priest has created SINK, “a model of anthropogenic ocean acidification”.  The materials used are a scallop shell, an internal combustion engine, glass walls, aluminum framing, copper piping, brine and methanol.

How it works: “Fuel is burnt by an internal combustion engine to turn a propeller. The carbon dioxide rich exhaust gasses are piped into a tank containing brine and a scallop shell. The dissolved carbon dioxide creates carbonic acid and increases the acidity of the brine. The calcium carbonate in the shell slowly begins to dissolve.”
