Molding Sand: Types and Properties [PDF] - Learn Mechanical

Green Sand: The green sand is tempered sand and contains enough amount of moisture. Greensand contains a mixture of 15% to 20% of clay, 6% to 8% of water and silica. Strength depends on the mixture of water and clay. The mixture acts as the bonding material in the sand. Greensand mold is that mold which is basically made from Green Sand.
