Hi, Hoping someone can help me. I’ve recently have been having
problems with “shadowing” on sterling silver. When polishing, after
it is nice and shiny, there are dark spots on the surface. Not just
the polishing compound. They do polish off but I’m wondering why its
happening. I can’t recall having this problem in the past but I
usually use a tumbler if at all possible. I am using Grey Star
polishing compund. I don’t know if it is residual firescale and need
to pickle longer, or if the piece is getting too hot during
polishing or its the compound or what.
Please help -
