I’d like to try etching silver. I’d like to be able to create some
deep marks - possibly even going all the way through to the back,
with the most vertical sidewalls possible. I believe that the correct
way to express this is that I am looking for an “anisotropic” etch
that does not “undercut” the masking layer.
Which is better in this regard: electro-etching or chemical-based
And is there any difference between Argentium and conventional
sterling silver when it comes to etching?
