Help! I recently bought stainless steel shot for my double barrel Harbor Freight tumbler which I have owned for a few years but only used once and never got jewelry until now.
I have put this pile of sterling ear wires and rings in and they keep coming out black.
I have tumbled them at least 4 times at varying lengths (45 minutes up to 12+ hours) putting fresh burnishing mixture in each time and cleaning well.
What am I doing wrong?
