The spin casting process typically uses vulcanized silicone or organic rubber as the mold-making substrate. Vulcanization is an integral step that occurs halfway through the mold-making process. Prior to vulcanization, the mold rubber is a soft and malleable solid-like fluid, in many ways very similar to Silly Putty. Because of the clay-like ...
The creation of a toy or figure start with the traditional sculpting process where the artist designs a clay sculpture. Where appropriate, for example when making a garage kit, the sculpture is dissected into several parts like head, torso, arms and legs. A flexible mold made from room temperature vulcanized (RTV) silicone rubber is made for ...
A versatile medium for artists of all ages, modeling clay is easy to shape with your hands and does not need to be fired to create a permanent form. The clay softens up in response to body heat ...
However, largely because sulfur interfered with some mould-making processes, especially if clay surfaces are unsealed surfaces and platinum-cure room-temperature–vulcanizing silicone was used, sulfur-free variants are now available; these are usually much lighter than sulfur-containing clays.

A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. [2] The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object.
properties of the mold material, such as permeability, and; moisture content of the mould. Schematic of the formation of a cast piece. The casting slip is poured into a porous mould. Due to capillary pressure from the mold, a semi-solid particulate layer is formed on the mould through deposition of the solids in the slip.
