Ridgewayforge Posted June 1, 2012 Share Posted June 1, 2012 I have a few pieces of steel which have a warty build up on their surface. I chipped away a little bit on one, and it left the nice steel underneath. Does anyone have an idea as to a) what this build up is and b ) how to remove it best. Thanks! ~Ridge Quote Link to comment Share on other sites More sharing options...
divermike Posted June 1, 2012 Share Posted June 1, 2012 Just a guess, maybe scale? was it in a gas forge? some slag from the foundry? Quote Link to comment Share on other sites More sharing options...
Ridgewayforge Posted June 1, 2012 Author Share Posted June 1, 2012 No, these were pieces that I found laying on the ground by the side of the road or partially buried in some dirt. I'm thinking it might be a chemical reaction. I'll see if I can get pictures after the rain stops. These items were never placed in a forge (yet!).

bigfootnampa Posted June 1, 2012 Share Posted June 1, 2012 Rust? The salt used on roads will often accelerate rusting. Try washing in ammonia and water to neutralize and then heating in the forge should take care of the rest. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 1, 2012 Share Posted June 1, 2012 Rust can be quite crusty; I recently found a mooring cleat at a scrapyard out here in the desert and have been chipping off rust crud over 1/4" thick---I'm saving it to try it in my bloomery...

ciladog Posted June 2, 2012 Share Posted June 2, 2012 I started using electrolysis to remove rust and scale from metal. It also removes paint, oil, and grease. I had read about it but always thought it wasn’t worth the trouble when the angle grinder with a wire wheel was always so handy. Well I finally tried it and it was so simple that even I could do it. :) And no more rust dust to breathe either. It is so effective that I’m thinking of getting rid of my sandblast cabinet.Here is a video link that explains it simply. This guy uses carbon anodes but iron or steel works just as well.http://www.youtube.com/watch?v=QOx5URgjTiU&feature=plcp Quote Link to comment Share on other sites More sharing options...
Ridgewayforge Posted June 3, 2012 Author Share Posted June 3, 2012 Okay, I guess I've just never encountered rust in such built-up forms. But I guess that makes sense, becuase it is a chemical reaction. I might have to try that electrolysis someday, Ciladog! Thanks for the help and happer hammering!

nuge Posted August 21, 2012 Share Posted August 21, 2012 Great videos! Thanks for that link. So tempted to check out the sun dried tomato gravy and pork jowl omelette but cant spend the 21 minutes. Any ideas about a source for carbon hunks? Would old water filters work? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 21, 2012 Share Posted August 21, 2012 No you need block carbon not powdered or granular Quote Link to comment Share on other sites More sharing options...
