bluerooster Posted April 12 Share Posted April 12 I got started thinking about all the scale around the anvil. And the thought came to me to build a clay furnace, and toss all the scale into it and see what comes out. I'll fire it with charcoal, and see if I can create a bloom of forgable steel. Also what about tossing in clinker as well. Clinker contains a mix of scale, flux, dirt, etc. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted April 12 Share Posted April 12 I would leave out the clinker Quote Link to comment Share on other sites More sharing options...

bluerooster Posted April 12 Author Share Posted April 12 Yeah, I guess I will. Too much unwanted stuff in clinker. Quote Link to comment Share on other sites More sharing options...
Frosty Posted April 12 Share Posted April 12 A large part of the bloomery process is getting rid of slag like clinker. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
George N. M. Posted April 12 Share Posted April 12 Since the clinker is primarily impurities from the coal and largely composed of silicates which are the result of sand and silt (mud) washing into the coal swamps there will be little iron in it. Just the bit of scale it picks up in the forge. So, about all you would get is more slag to pour off the bloom with little gain in the amount of iron. BTW, I expect that the bloom will be pretty much iron rather than forgable steel. I expect that you will have to work it down into wrought iron. The scale is pretty much iron oxides which will approximate iron ore. So, the process will be very close to getting metal from ore. "By hammer and hand all arts do stand."

Nobody Special Posted April 12 Share Posted April 12 My one contribution is that unless you're forging all day most days, it's gonna take you a long minute to get enough scale. The last bloom I did took a lot of ore, I can't imagine collecting enough scale flakes to make anything more than a mini-bloom. You're in northern Georgia, right? If you want to make a bloom, there's a crap load of good goethite at and around Red Top Mountain, in huge fist size chunks that you can easily pull out of the red clay banks. I used to ruck it out in my ALICE pack. It was mined heavily there up through the Civil War. They still mine red ochre up there. Heck I've got some of it here in WA, not to mention a bit of mostly cooked bloom (unexpected GA thunderstorm and stupidly hot clay furnaces don't mix). If you're not near there, there's iron ore practically everywhere in North Georgia. I used to see limonite all over near Macon. Quote Link to comment Share on other sites More sharing options...
SubterraneanFireForge Posted April 13 Share Posted April 13 Yeah I’m also curious as to how you are getting that much scale. I’ve been thinking of trying a similar thing with all my lil bits of scrap metal. if it you blooming works out I might have to start hoarding scale to. definitely let us know how it goes and take pictures if you can!

Frosty Posted April 13 Share Posted April 13 Put a magnet in a plastic bag and pass it around your anvil, floor, yard, pickup bed, etc. when it won't pick up more turn the bag inside out over a bucket and put the magnet in another bag. When you stop getting filings, scale, pinch offs, etc. Go visit another blacksmith. Lather rinse repeat. When you have say 20lbs or so you might get a 4lb bloom. Frosty The Lucky.

gewoon ik Posted April 14 Share Posted April 14 Thomas told once he used scale and grinddust. Can't remember where on ifi i read it. Quote Link to comment Share on other sites More sharing options...
Frosty Posted April 14 Share Posted April 14 He did and also said the amount of steel cuttings was enough of a higher % than the bits of broken garnet, silicon carbide, etc. from the belt as to make little if any difference. We had a good discussion about it a while back. It's in the sections. . . somewhere. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
