Greetings Orchidians!
I am curious on the process of blackening cobalt chrome.
I am making a ring for a client and the intended look is a deep black
that will stay hard and black. There will be a rose gold inlay and
two gems riveted to the piece.
I was quite surprised to search online and through the
Orchid/Ganoksin archives to no avail.
Cheers,
Justinder
