Green sand is the most commonly used sand in the casting industry. It is a mixture of silica sand, clay, water, and various additives. The term green refers to the state of the sand when it is wet and pliable. Green sand has excellent molding properties, allowing it to hold intricate details and withstand high temperatures during the casting process. Its composition often includes around 10% clay, which helps in binding the sand particles together, providing strength to the mold. This type of sand is primarily used for iron and steel castings and is favored for its cost-effectiveness and availability.

Lost foam casting is a more specialized type of sand casting that uses a foam pattern instead of traditional metal patterns. The foam is coated with sand and heated, causing it to vaporize while metallic material fills the void.
