Re: [Biofuel] lye electrolysis for rust removal
Hi NS I have used this 'electrolysis method' of rust removal many times. It is very effective and useful for recovering 'old bits of iron' and bringing back some iron machinery back to life. However, it should be kept in mind, that once the 'iron' has corroded or rusted off the item, it is gone for good and adding 'zinc' or other things to the electrolyte does nothing to restore the iron artifact to original. It means, once the artifact has been pitted or the rust so sever whereby the iron is removed, it cannot be replaced. Electrolysis simply cleans down to the iron that has been left untouched by the action of rusting, it replaces nothing. That's quite right, my own experience too. If there's enough steel left for the tool still to be useful, then go ahead, but if it's too deeply pitted, forget it. Electrolysis won't repair anything, it only removes the rust. Matthew Gilbert sent me this helpful info: http://www.holzwerken.de/museum/links/electrolysis_explanation.phtmlhttp://www.holzwerken.de/museum/links/electrolysis_explanation.phtml has the following to say about the black stuff: Typically the black stuff that can be rubbed off after electrolysis is a mixture of iron metal and magnetite, Fe 3O4 , an oxide of iron. This site gives a pretty good description of the chemsitry of derusting. http://en.wikipedia.org/wiki/Ferrofluidhttp://en.wikipedia.org/wiki/Ferrofluid http://en.wikipedia.org/wiki/Magnetitehttp://en.wikipedia.org/wiki/Magnetite explain the formation of a fluid of magnetite when in the presence of sodium hydroxide... HTH - best Keith I am not an expert scientist on this process, only experienced from what I have done with using this method over the years. cheers!

Re: [Biofuel] lye electrolysis for rust removal
hi, all, thanks for the replies. i do understand that it won't restore an item to original condition. i was just curious why some would choose to add zinc to the lye bath. seems sort of. . .i'm not sure what word i'm looking for. just seems to needlessly complicate things. keith, you linked to the same archive entry i did :) anyway, thanks again for the comments. ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/sustainablelorgbiofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (70,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
