2007-10-8 The typical foundry sand is a mixture of fresh and recycled sand, which contains 90% silica (SiO 2), 3% water, and 7% clay. The grain size and grain shape are very important as they define the surface quality of casting and the major mold parameters such as strength and permeability: Bigger grain size results in a worse surface finish
