SAND, SAND ADDITIVES and SAND PROPERTİES
` Coarse and uniformly graded sand imparts high permeability, good refractoriness and high flowability. ` Normally the foundry sand possess the grain size between 0.1 to 1.0 mm ` The fine grained sands are used to make intricate and small size castings. ` Coarse grained sands are used to make large castings.

How does sand form?
Black sand comes from eroded volcanic material such as lava, basalt rocks, and other dark-colored rocks and minerals, and is typically found on beaches near volcanic activity. Black-sand beaches are common in Hawaii, the Canary Islands, and the Aleutians. The by-products of living things also play an important part in creating sandy beaches.
