A broken Thread.
Hi Hannah Mary,
This method using a battery and salt appeared on the forum last December, posted by surfgirl. I have been unable to locate it today, so here is my copy, scanned in. I believe it works on various metals including copper, brass and silver.
If you do not find this sufficient and you PM me, I can send you photocopies, plus more detailed stuff I have from another source. Dennis.

The saltwater etch method first appeared in an issue of Art Jewelry a couple of years ago (from memory) and is still available as a download from them. There are also a couple of free blogs featuring the same technique. I've used it for copper and brass, but have yet to see good results on silver, even with the expensive Sherri Haab kit.
You could also try Edinburgh etch, there are numerous recipes around.
I have to admit that on the rare occasions I do any etching, I put on my big blue gloves and head outdoors with my nitric acid and goosefeather!

So, what are the advantages of using nitic acid (which sounds alarming) over ferric nitrate (which sounds much less so) to etch sterling silver? I'm thinking of doing at etching course at London Jewellery school, but don't really want to play with nitric acid at home unless I really have to.

I just find nitric quicker and crisper.
