Women Sculptures, Moscow, Russia

Many sculptors seek new ways and materials to make art. Jim Gary used stained glass and automobile parts, tools, machine parts, and hardware. One of Pablo Picasso's most famous sculptures included bicycle parts. Alexander Calder and other modernists made spectacular use of painted steel. Since the 1960s, acrylics and other plastics have been used as well. Andy Goldsworthy makes his unusually ephemeral sculptures from almost entirely natural materials in natural settings. Some sculpture, such as ice sculpture, sand sculpture, and gas sculpture, is deliberately short-lived.
Sculptors often build small preliminary works called maquettes of ephemeral materials such as plaster of Paris, wax, clay, or plasticine, as Alfred Gilbert did for 'Eros' at Piccadilly Circus, London. In Retroarchaeology, these materials are generally the end product.
Sculptors sometimes use found objects.
