What are Green Sand Castings? - Willman Industries

The green sand for the casting molds usually has a mixture of: Sand = 75-85%. Bentonite Clay = 5-11%. Water = 2-4%. Other materials = 3-5%. Silica in the sand can become airborne in the process of casting so American foundries install air control systems that pull the silica particles and anything else out of the air to keep foundry workers safe.

Foundry Manual - Part 2

A mold is made by shaping a suitable sand mixture around a pattern of the desired form. A metal or wood box (flask) is used to retain the sand. The pattern is then removed from the sand, leaving a cavity in the sand into which the molten metal can be poured. The molder's skill is the basic skill of the foundry.
