chemical rust treatment, alchemy

[richsc]

I am not too sure how much chemical knowledge the Romans had, and not too sure where to look for sources. The idea of chemically protecting iron from rust using chemicals, especially something called "jeweler's pickle" , seems to be a low tech means of putting an anti-oxidation anti-rust coat on iron. I'll be trying this out, trying to add a coat (if you can call it that) of copper to iron.<br>
<br>
I was wondering if those ancient 'batteries', however, could have been used for a type of electroplating.<br>

I've ordered some jeweler's pickle and will be experimenting with it in a few weeks. <p></p><i></i>
