Quote:Well, I've never bothered pickling and polishing until the shaping is done. Doesn't seem to be any point! Why pickle if you're just going to be annealing again in a minute or two? Aside from the fact that I usually have to do some grinding/filing/sanding after shaping, which makes pickling irrelevant.
Sometimes there is a point. If you anneal brass and then put it through a rolling mill without cleaning the oxidation (either mechanicaly or by pickling) the oxidation will be rolled into the surface and it will not be possible anymore to remove it by pickling...
I know that their is no certainty about the use of a rolling mill by the Romans, but this is irrelevant to the point I want to make :wink:
