Roger Hiorns investigates alchemical transformations of ideas, actions and materials. Organic matter and chemical compounds and processes – brains, fire, crystals, sperm and drugs – are introduced into man-made structures, among them buildings, engines and street furniture. His crystallisations of copper sulphate have produced encrustations of ultra-blue on car engines and, most spectacularly, invaded a council flat in South London.

In this work, Hiorns places a generic municipal bench in the gallery. At unspecified intervals, a flame will flare at one end of the bench, occasionally tended by a naked young man.
