Regarding pickle – It’s been some years since I had to stop
enameling, due to the loss of the facility where iI was taking
classes. But I hope to be getting into it again one of these days.
This talk of not using an acid pickle, or not putting your work in
acid, sounds puzzling to me, as we used a (dilute nitric) acid bath
after enameling on copper, to get rid of fire scale on the side that
had not yet been enameled. Is this no longer done? (Or something that
should no longer be done?) If so, how do you now get rid of the fire
scale ? (We were mostly doing larger pieces, such as bowls of various
sizes.) Or do I misunderstand, and you are talking about a different
kind of (or reason for) pickle(ing)? And, if so, what?
thanks in advance for enlightening me!
