Hello. I’ve decided to switch from ferric chloride to salt water for
etching base metals, copper, brass, bronze, nickel. Since I have an
18 amp rectifier, I plan to use that. I’ve only used the rectifier
once for electroforming so I’m not that familiar with it. Can
someone advise on the best voltage and current settings for salt
water etching? I’ve google searched but so far can’t find anything
on that specific issue.
Several years ago I salt etched with a rectifier in an enameling
class and had good results. I took good notes. Only problem. not
sure what I did with the notes!
