What "ingredients" would you find in greensand?

Question

Does anybody know what makes up greensand used in greensand casting.

Answer 1

The green colour of greensand is due to variable amounts of the mineral glauconite, an iron potassium silicate with very low weathering resistance.

Answer 2

Greensand is an olive-green coloured sandstone rock which is commonly found in narrow bands, particularly associated with bands of chalk and clay worldwide; it has been deposited in marine environments at various times during Earth history, such as during the Jurassic and Cretaceous periods.

The green colour of greensand is due to variable amounts of the mineral glauconite, an iron potassium silicate with very low weathering resistance. Greensand is a common ingredient in garden fertilisers. It is also used directly in organic gardening and organic farming. Due to its chemical exchange properties, the glauconite of greensand is used as a water softener.

In some areas, a distinction is made between Upper Greensand and Lower Greensand. These greensand strata tend to occur just beneath the chalk and can be separated by a layer of Gault. Greensand is quite common in northern and western Europe. In Britain, prominent seams are to be found in the Vale of White Horse, the Greensand Ridge in Bedfordshire, the Greensand Way in Kent and the Jurassic Coast in Dorset.

Greensand coated with manganese oxide, known as manganese greensand, is used in well water treatment systems to remove insoluble ferric (oxidized) iron and manganese.

Answer 3

Green Sand is an aggregate of sand, bentonite clay, pulverized coal and water. Its principal use is in making molds for the casting of metals.

Answer 4

Green sand is a naturally occuring substance. I am not sure what it has. I can't find it in my books. Try Google.

Answer 5

Pele's Tears,olivine and peridot make up green sand.
