Armature (sculpture)

In sculpture, an armature is a framework around which the sculpture is built. This framework provides structure and stability, especially when a plastic material such as wax, newspaper or clay is being used as the medium. When sculpting the human figure, the armature is analogous to the major skeleton and has essentially the same purpose: to hold the body erect.
An armature is often made of heavy, dark aluminium wire which is stiff, but can be bent and twisted into shape without much difficulty. The wire is affixed to a base which is usually made of wood. The artist then begins fleshing out the sculpture by adding wax or clay over the wire. Depending on the material and technique, the armature may be left buried within the sculpture but, if the sculpture is to be hollowed out for firing, it must1 be removed.
Large representational sculptures meant for outdoor display are typically fashioned of bronze...
