of bearing metal alloys, it is easy to convert ingots to liquid alloy. To make molten metal suitable for casting, however, requires careful control. The melting pot can be of any size suitable for the amount of metal needed. Heatresistant iron containing nickel, chromium or molybdenum is the preferred material for its long service life.

Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb2S3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
