refractory is left on the sand surface. This layer or barrier can prevent or minimize the penetration of molten metal into the sand, can reduce or prevent "burnon" and erosion of the sand and generally improves the quality of a casting surface. The benefits of a foundry coating are only achieved if the coating is the proper one for the job and
Greensand molds are used for normal foundry work aboard ship. They have the necessary green strength and other properties which make them suitable for a great variety of castings. Green sand gives less resistance to contraction of a casting than does dry sand.
Sales of foundry sand have decreased in recent years due to the demise of engineering in the UK. About 11% of the sand sold in 2004 was used for foundry purposes. Foundry moulds are mostly made from a mixture of silica sand chemically bonded with or Furanes etc. : bentonite and water. Much of this material is now recycled for reuse.
