SAND, SAND ADDITIVES and SAND PROPERTİES
Permeability. Heat from the casting causes a green‐sand mold to evolve a great deal of steam and other gases. The mold must be permeable, i.e. porous, to permit the gases to pass off, or the casting will contain gas holes.

Green Sand: Key Uses in Foundry Applications
Green sand casting is a simple, scalable and resilient method for the casting of metals. Casting itself is a millenniums-old technique(4). Depending on the choice of sand, the process can be incredibly inexpensive, particularly if silica is the major sand component due to its abundance.

1.2.2 Dry-sand molding Dry-sand molding is similar to green sand molding in that moist sand is used to initially form the mold. The green sand mold is then dried by baking it at 400 to 6000F (or 204 to 3160C ) to develop good strength and other properties. Generally the mold cavity surface is coated or sprayed with a mixture that increases the
