Hey Guys,
I want to etch some copper. I bought some ferric chloride anhydrous, thinking that I would rehydrate it as and when I needed it. However, when I searched for info on how to mix it up, I couldn't find much on the Internet. Then I came across an article saying I should have bought hexahydrate to do etching, not anhydrous. Any chemists out there know what is the correct type for etching?
Thanks,
Steve
