Jonathan Clarke works in sand-cast aluminium, initially carving his sculpture in polystyrene. This method relies on the destruction of the original mould as it is vaporised by molten aluminium. The result is an entirely unique, one-off sculpture.
The ‘lost polystyrene’ method adopted by Jonathan means that each cast is a unique, one-off sculpture. He slices through a block of polystyrene with a hot wire, carving individual components with which to assemble the finished piece. The polystyrene is then buried in special moulding sand before the pure, molten aluminium is poured in. The polystyrene mould is instantly vaporised, leaving the aluminium cast to solidify in the sand.
