Time-based work made for Bonnington Gallery, Nottingham 1994: An open copper box sat in the middle of the floor in the gallery. Copper sulphate solution in nine boxes sitting on a shelf evaporated over time by methylated spirit in the bottom tray. People were invited to stay and contemplate the flames that changed colour as the copper sulphate solution burned off. A soundtrack of harmonics made in the gallery played from the duration of the time the mentholated spirit burned out and the flames died.
