In LOST WAX CASTING, the armature, which extends from the base up into part or all of the sculpted composition, should be distinguished from the core supports, which are separate, shorter pieces of wire or rod added to strengthen isolated sections of the core. An armature serves both to bear the weight of the sculpture and to maintain the positions and forms of the compositional elements as the sculpting material hardens. Wires or padding are attached to the central component to support projecting forms such as limbs. The armature usually consists of a central, rigid element onto which the main mass of the sculpture is MODELED. Metal armatures are also used as internal supports for large metal monuments.
7)Īn internal skeleton, usually of metal or wood, which supports a sculpture in clay, plaster, or other modeling material during its construction. Although this deficiency can be somewhat compensated for by careful CHASING, it nevertheless explains why aftercasts are usually considered to be of diminished quality. The process of taking molds from an existing bronze may result in the softening or loss of surface detail. To learn about sculpture techniques and tools, see: Inside Lachaise's Toolbox: Documenting an installation at the Portland Museum of Art, November 2020, (15'53).Ī bronze sculpture cast using MOLDS taken from a pre-existing work in bronze rather than from the original MODEL.Īn aftercast is later in date and slightly smaller than the bronze from which it was derived the reduction in dimensions in the aftercast occurs because molten metal shrinks as it cools.
