Metallurgy - Casting, Alloying, Refining

Metallurgy - Casting, Alloying, Refining: Casting consists of pouring molten metal into a mold, where it solidifies into the shape of the mold. The process was well established in the Bronze Age (beginning c. 3000 bc), when it was used to form most of the bronze pieces now found in museums. It is particularly valuable for the economical production of complex shapes, ranging from mass-produced parts for automobiles to one-of-a-kind production of statues, jewelry, or massive machinery. Casting processes differ in how the mold is made and in how the metal is forced into the mold. For metals with a high melting temperature, stable refractory
