Blackening or “bluing” is an old-school technique for creating a one-of-a-kind, hand-crafted finish on steel, stainless steel, and aluminum.
Similar to staining wood, blackening alters the chemical make-up of metal providing unique hues and a corrosion resistant patina that protects and locks in its distinctive character.
And today’s process offers nearly every color you can imagine including yellow, green, red and bronze in a whole variety of shades.
