In the sand casting process, a sand mixture is packed around a master pattern, forming a mold cavity. The sand mixture is tamped down as it is added around the pattern. The pattern is removed leaving the mold cavity and molten metal is poured into the mold cavity. After the metal has solidified and cooled, the casting is separated from the sand mold. There is typically no mold release agent, and the mold is generally destroyed in the removal process.
