Here is an excerpt from the Green Sand section page on Metal Casting Zone:

“Green Sand: Green sand is also called as foundry sand or molding sand. This is utilized for sand casting. When this sand is oiled or moistened, it has a tendency to pack well and retain the shape. Green sand is a mix of pulverized coal, water, bentonite clay and sand. Out of these four components, the biggest part is that of the sand.  There are several proportions of these four components. The different ratios are used to adjust the surface finish, moldability and capacity of the hot molten metal to degas. The prime use of this sand is in the metal casting. The coal is usually called as sea coal in foundries. The amount of sea coal is less than 5 percent. It undergoes partial combustion when there is molten metal present and this causes offgassing of organic vapors.

Green sand is stored in flasks (as the casters call the container). These are boxes that do not have a bottom or lid. This box is divided into two half parts and these are connected together. These halves are called as the top or cope and bottom or drag flask.”
