Re: Problem with black
Is the rod shiny black or a raspy coarse feeling black? One is moretti black and the other is moretti silver plum which is intended to turn metallic silver color. Some people have reported that latest moretti shiny black is also turning silvery color too. Usually the silvering ocurrs when you are using too much oxygen in the mix, assuming you are using a torch rather than a hothead.
If you have the latest shiny black, some people are lightly etching beads to remove silver finish. This is a real quick dip into the etching fluid - not to really etch, etch them. Another person found using a stained glass super brite copper patina dunk, help clean the scummy silver finish would remove it from their black bead. Try all three, starting with oxygen regulating first and see if that helps. Good luck
