I'm contemplating buying a rectifier for etching copper and silver. I don't actually know how to etch, but was wondering if anyone had a tutorial online using galvanic etching or could take a picture of their set up. Thank you!
I use a car battery charger, cupric sulfate (root kill from home depot) , anode and cathode. Super easy to do...i used a very thick copper sheet (from industrial metal) as the cathode, the alligator clips are the anode.
no, the cathode is still the thick copper, but you use a different chemical - cupric nitrate aka copper nitric one source is Atlas Chemical. Silver etches faster than copper, so you have to watch it.
