Clay & Wax Modeling

Industrial plasticine is based on wax and typically contains sulfur, which gives a characteristic smell to most artificial clays. Often, the styled object will be used to create molds. However, largely because sulfur can interfere with some mold-making processes, especially if clay surfaces are unsealed surfaces and platinum-cure RTV (room temperature vulcanizing) silicone rubber is used, sulfur-free variants are now available; these are usually much lighter than sulfur-containing clays.

Modelling clay is a group of malleable substances used in building and sculpting. The material compositions and production processes vary considerably.
  • Ceramic clay
  • Oil-based clay
  • Polymer clay
  • Paper clay

Clay & Wax Modeling Samples

Oil Clays are made from various combinations of oils, waxes, and clay minerals. Because the oils do not evaporate as does water, oil-based clays remain malleable even when left for long periods in dry environments. Articles made from oil-based clays are not fired, and therefore are not ceramics. Because the viscosity of oils are inversely related to temperature, the malleability can be influenced by heating or cooling the clay. Oil-based clay is not soluble in water. It can be re-used and so is a popular material for animation artists who need to rework their models. It is available in a multitude of colours and is non-toxic.
