Mr Levy you might want to suggest what he (and I) should use for that sacrificial anode.
Is this to be some metal that corrodes faster/is less noble than iron? And is available in the strip or bar you need?
I have some old cast iron, specifically a fragment of a cast iron 11 inch shell, delivered to Fort Fisher, North Carolina, C.S.A., January 15, 1865 by the Federal fleet under Captain Kidder Randolph Breese. Wouldn't mind trying your process on it. So far I have only rinsed it well in tap water to get rid of some salt, which I presume may be present given the location.
Electrochemistry never sunk in to me.
