Learn about Casting Resin, Resin Casting and the Basics of
Metal Casting

casting is known and loved for the high temperatures, glowing molten metal, and
the possibility to make nearly anything. Metal and their alloys are not the
only things that can be used in casting. Casting in plastic, most notably resin
casting, is becoming popular with artists and jewelers looking for something
odd and unique.
Resin casting does not involve the use of furnaces, crucibles, or casting sand.
In fact all one really needs for resin casting is a mold, some resin (of
course), and time.

Learn about the basics of Casting Sand, Green Sand, and the
uses of Casting Sand.
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.
