Electrical etching


#1

Could someone give me some on electrical etching and how
to make one. I have used ferric chloride for copper and would like to
find another way to etch without using chemicals. Any help would be
apprecitated.

Hi,

I have just the thing you’re looking for, an electrolytic etching
tutorial I just finished writing a few weeks ago:

If you have any questions, feel free to ask. The chemicals are
pretty safe and if you really really don’t want to use chemicals I’ve
heard you can use salt.

One note is that I have had random luck with silver (I’ve only done
it twice). On a small ring it came out perfect, but on a bigger
pendant it left a sort of holey texture in the etched away parts.

Good luck! m

Roxane,

This topic just made the rounds in the “enamelforum” on yahoo groups.
Check out the recent discussion at
http://groups.yahoo.com/group/enamelforum/. Two recently posted files
"Electro-Etching_with_a_Plating_Rectifier.pdf" by nonabee and “My
Electro” parts 1&2 by verameyer12 contain a lot of useful info.

Regards, Tom

Roxan, the November 2008 issue of Art Jewelry magazine has an
article, “D Battery + Saltwater: Cheap, Acid-Free Etching.” It works
on copper, brass, bronze, and nickel silver. When I get the time,
I’m going to try it!

The thing that most “home made” articles never tell you is the
correct temperature to do the etching at. For some etchants it will
be sub-zero and others close to boiling point. This will make a big
difference to the surface finish. Another trick is to gently wipe
the metal surface with a feather whist etching to remove gas bubbles
and insoluble salts. This again will improve the finish and lend
itself to curing the problem of larger surfaces being unevenly
stripped.

Thank you, thank you, thank you.

This is going to provide endless hours of messing about in the
workshop!
