Wurzeln, 2005

polyurethane, diverse formats

In conjunction with their large retrospective Flowers & Questions in London, New York, Hamburg and Zurich, Fischli and Weiss added two large tree roots to their series of rubber sculptures: one smaller root with a squat, compact format, and one larger root, weighing round two-hundred kilograms, fissured on one side and cut with a saw into a geometric form. Silicon negatives were produced for both of them and these were cast in black polyurethane (synthetic resin)  – a complex procedure in the case of the larger root due to its frayed surface. The core consists of foam glass, a material that, in contrast to synthetic foams, is not prone to shrinkage or to chemical reactions.
