Thanks myv65, that's a lot of good info.
Oxidization is definitely not the same as galvanic corrosion.
What hasn't been covered yet is acid corrosion: the attack on metals from H+ or OH- ions (the components of H2O). with Copper, which forms a Cu (+2) ion, the OH- attacks it, or pulls the copper atoms from the copper block.
Keeping a solution neutral would seem to be the way to go, off-hand, but on the other hand, I wonder what would happen if the solution was more acidic (lower than 7 pH) versus more of a base (higher than 7 pH level). pH? (oops, I mean pHaestus?)
