Blacking copper creates a non-reflective, glare-reducing surface, it is a chemical conversion process that produces a darker finish,. The treatment reacts with the surface to form a stable, dark oxide/sulphide layer without adding measurable thickness, enhancing appearance while providing mild corrosion resistance. It can produce an antique-style finish on copper and copper-based alloys such as brass and bronze.
