Casting takes a material that is in a flowing or liquid state and puts that material into a container or Mold that restricts its flow until it stops flowing. The method for stopping the flow can be either temperature or chemical based.

For example, in slip casting of clay, when the clay dries it no longer flows and can be removed from the mold.
