A trip through a foundry from pattern to product. This series follows a cast iron or steel product through the metal casting process in a traditional foundry. Iron melts at 2750°F and steel at 2500°F. Casting is the process of creating metal objects by pouring liquid metal into molds, where it cools and hardens into the mold's shape.

A replica of the desired metal item is pushed into foundry sand, where it creates a hollow "negative" of the object. That void is filled with molten metal, capturing its details. When the void cools, the metal object is pulled from the sand, with the original design faithfully captured. Anyone who has built a complex sandcastle or sand ...
