The more common, called chromite, is a dark, dull stone that was easily overlooked. The second, a mineral called crocoite, is unusual in appearance but extremely rare. Chromium is a silver-white metal with a high melting point.

Chromium is a chemical element with the atomic number 24 and the symbol Cr. Among its most defining factors are a shiny grey-silver color, extreme hardness, and very good chemical resistance.

Pure chromium is magnetic and brittle, but when alloyed can be made malleable and polished to a bright, silvery finish. Chromium is a steel gray, lustrous, hard metal extracted from chromite ores. In 2011, U.S. production of chromium was estimated at 160,000 metric tons, coming almost entirely from recycling stainless steel scraps.

Chromium metal is primarily used for its ability to help steel resist corrosion and increase hardness. What we commonly refer to as stainless steel is actually composed of over 13.5 percent chromium. The metal can be produced using three methods: (1) an aluminothermic process, (2) a silicothermic process, or (3), an electrolytic process.
