Excerpt from Shop and Foundry Practice, Vol. 4: Prepared for Students of the International Correspondence Schools Scranton, Pa

1. The production of ordinary metal castings, such as those of iron or brass, involves three distinct operations. First, a form is made very nearly like that required in the casting. This form is made of wood or some other easily shaped material, and is called the pattern. Next, from this pattern a mold is made in sand or in some other substance that is refractory enough to withstand the action of molten metal. Lastly, the metal is melted and poured into this mold. Each of these operations requires special skill, and has given rise to a special trade, though the latter two - the molding and founding - are often performed by the same person.

These operations are sometimes so intricate and admit of so much variety that the above statements are true only in the main. The molder may make his own pattern out of clay, or, if it should be necessary to use it a large number of times, he will make it of some hard metal; or he may make the mold itself, or a portion of it, of metal; and so on through a multiplicity of changes that are constantly occurring where a business is made of producing a variety of castings.
