Black Chrome or Nickel plating
How do I go about plating copper water pipe with soldered joints, to get a black chrome or black nickel finish? I want to used the finished article as a solar collector plate, hence the "black" finish required.
Kind regards

In the USA virtually all platers rely on proprietary supplier formulations, but if you search the site very patiently you will find a formulation suggested at least once. Black chrome is ideal, but even regular chrome is pretty good and would probably be significantly better than black nickel. Solar energy works a little different than our eyes, and chrome is a good solar absorber material even though it looks bright,
