Casting involves pouring liquid material into molds made from ceramic materials, polymers, metals, plaster, rubber, wood, or composites. The mold is an exact negative copy of the object to be cast. Often, solid materials (like iron or thermoplastics) must be melted before being cast. Sometimes, as in the case of plaster, slip (liquid clay), and concrete, the materials are mixed cold and poured into the molds (or forms in the case of concrete) where they harden.
