B/Ox 327 is a liquid concentrate non-selenium based process that produces a gunmetal blue, black, brown, and slightly purple finish.
Depending on the substrate, immersion time, and concentration, this oxidizing solution creates a variety of finishes on copper, brass, bronze, white metals, silver and tin-lead alloys.
B/Ox 327 is a liquid concentrate diluted with water and used at room temperature as an immersion "oxidizing" solution. The color, depth of color and reaction rate is controlled by varying the concentration and length of immersion.
