Ferric Oxide (Fe₂O₃), also known as Red Iron Oxide or Jeweler’s Rouge, is a premium-grade abrasive powder used throughout the gold refining, jewelry, and metal finishing industries.

This ultra-fine red powder is valued for its consistent grain structure and strong polishing ability, producing a mirror-like finish on gold, silver, platinum, brass, and other precious or base metals. Ideal for final-stage polishing, buffing, and surface preparation, it removes micro-scratches and oxidation without damaging the underlying metal.

Beyond refining applications, Ferric Oxide can also serve as a colorant in concrete, glass, ceramics, and enamel formulations due to its rich red pigment and stability at high temperatures.
