Iron melts at about 2,800 degrees Fahrenheit. Sand won't melt until the temperature is roughly 3,000 degrees, making it a perfect holder for molten iron. But at Poitras Foundry, sand alone won't stand up to the pressure and heat of making quality castings. Our green sand is made of: -Silica sand to act as an insulator.
Definition and Composition Also called "glauconite," greensand is a material from the ocean floor that is mined to be used as a soil conditioner or fertilizer. 1 It has a bluish-green color and is made of marine potash, silica, iron oxide, magnesia, lime, phosphoric acid, and about 30 other trace minerals.

Greensand is a soil amendment that helps condition the soil. It works to loosen the earth and is especially good for improving compacted soil or heavy clay. The material goes down into the soil and pushes heavy particles apart. This makes the soil lighter, which provides room for roots to expand and allows air to circulate in the soil.
