Article excerpt from the TheMetalCasting.com.

Foundry sand is used for making castings, and is primarily generated by the automotive industry and its part suppliers. It consists of clean silica sand, which is of high quality; or lake sand, which is bonded to make molds for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. The following types of sands are used for making molds in the foundry industry: Green Sand, Resin Coated Sand, Molasses, Cold Box Sand, Hot Box Sand, and CO2 Sand.

These types of sand can be obtained directly from the foundries located in the Midwest states such as Illinois, Wisconsin, Michigan, Ohio, and Pennsylvania.
