  • I must say again that your idea about this "rocket" style nozzle for heat. Indeed, praise the Higher Power (a.k.a. God Almighty) for this invention. Some people don't seem to realize the implications of this ability to have less heat do a great deal. Thank you.

    I say this after preaching for 10+ years and in lieu of the slow car sticker moment, part time labels on clothes, say so, THE BOX, Future consciousness "thief" detection unit,, contact me, and publish on trans cans too.

  • does it absolutely have to be iron ore powder or would the shavings from machining brake drums/rotors suffice?

  • So badass. I've always wanted to learn the depths of metalworking, forging in particular. I hope I get to try this out one day.

  • Are there any books or publications that have plans or describe the process in more detail?

  • All steel is is iron ore and coke.

    The charcoal serves the same purpose.

    While this is not surgical steel by any means it is steel,

    Thanks for uploading.

    Any videos of projects made from this steel?

  • hi there, do you have instructions on how to construct on of these? also would iron sand work in one of these forges?

  • Rostfreier Stahl ? ? ?

  • NOT MAKING STEEL FROM DIRT... wtf you say that for? its iron from iron ore. Poor quality iron at that. Wanna reinvent the wheel next?

  • How long did it take to create that chunk? How much material cool sand and one last thing coast...?

  • Looks like a lot of hard, dirty work. But at the end of the process when you finally finish the last bit of grinding and polishing on your totally home-made knife it must be satisfying. Great vid.

  • I really want to do this. I've been obsessed with the art of making iron since I read about bloomeries and foundries as a kid. Sadly Florida isnt an iron bearing state. I have no source for iron ore or I would certainly give this a try.

  • so if i understand right you layer the charcoal, the charcoal powder and scrap iron in the shown way and thats how you end up with steel at the bottom from all of the massive temperatures?

    basically everything is being destroyed and what you are left with is ash and steel?

  • @dramey03 Only charcoal (chunks about 1 inch cube) and iron ore powder are going in the top. No "scrap iron", that would be a grappage furnace, and is used for different things and has a different design. This technique is very specific to getting Japanese-style steel bloom at the end.

  • not bad after 10 36 cases of beer and 5 25 foot tall trees in charcoal

  • man that's like alchemist stuff

  • what powder do you use

  • is charcoal better than coal? i think i once read somewhere it has more carbon than coal

  • @music1account charcoal burns at intense temperatures, up to 2700C, or 4900F. It also doesnt produce sulfur, which is why charcoal has been favored.

  • A TURBULENCE as in a "rocket nozzle" : absolutely brilliant!

    (I speak in addition to the slow vehicle movement, part t. and no hard schedules, The Box club, publishing on waste receptacles and cans with saying such at stores). AGA9N, BRILLIANT.... PTL Almighty for you on this!

  • I'm still a little confused about how you got the steel, layers of charcoal and powder, what is this powder? Also, where does the dirt come in? Is the dirt the powder?

  • @mynameismatt2010 It is the orange heavy rock you can pick up along river bed. you bake them then crush them into powder. The rusty orange rock is also known as hematite.

  • @mynameismatt2010 I agree with this. Maybe some labeling would be nice. Was it Iron powder going in through the top with charcoal? I have no metal working experience so I apoligize if it is a stupid question. but I found this video interesting and would like to know more about it

  • well... the patterns in a damasc-like forged blade isn't just a happy incident without any use, the different layers with molecular structures going in different directions gives far more flexible, resilient and strong blades than any ordinary steel. yes it also help the estetics, but damasc blades didnt't only get known for their appearance, but also performance.. just saying...

  • @Rhandahl That's kinda what he was saying. He was explaining that the folding process isn't just to make it look better, it actually has a funtional purpose.

  • is that layer is iron ore? Can somebody please explain the layers? Hard to catch.Thanx.

  • Awesome video but that man's gut absolutely stole the show!

  • If men were given more things to build, there wouldn't be time for war.

  • this is awesome. nothing like making something right from the beginning

  • HOw THE HELL DID I GET HERE i was watching fishing videos

  • OMG....I was watching this vid and my daughter saw it and had questions...so I grabbed a speaker magnet and took her outside and pulled about a teaspoon of metal from the earth including some pieces that looked like your blooms...now I have a question....can I use this metal after it touching a magnet?....really excited..didnt expect that much here in Michigan from the sandy soil.

  • "is it still molten in the middle"

    Touch it, bitch, you tell me.

  • @m3tz63r lol yeah i was waiting for the "its not quite like.. making cupcakes, dear..."

  • Nothing brings the men together like a huge lump of red hot steel. Cool video :D

  • How much is the steel? I want to make a sword and I am looking for some steel.

  • how much did all this cost to do? 500$-700$?

  • Good ol' cowboy brand charcoal...

  • at 6:05 some guys taking a piss XD

  • lol spongebob

  • thumbs up if you play minecraft lol

  • nice

  • wow, extracting iron from dirt:) minecraft would be easy like this!

  • @andresderasfriend Equivalent Exchange mod lets you do that :D

    Cobble works too :P

  • should be like this in minecraft.

  • As you mentioned with your 10 year estimate, modern weapons could become a thing of the past. BUT... once you have steel you have tools and from there it is just having the technology. Shot guns could be converted to flintlocks, lead could be scrounged for shot or just use 00 sized river pebbles. A supply of primers would be the big problem for modern weaponry.

  • Thanks for the video man! I'm trying to make some tamahagane out of black sands I collected from rivers in Ohio for small blades. I think this will do the trick!

  • What material did u use to build the forge? And where did u pick the dirt from?

  • @inkva I believe you can just get the black sands you need from rivers and streams. look up gold panning. black sands are usually a secondary product of gold panning and may be collected or purchased from prospectors.

  • minecraft led me here...

  • @CakeDuck112 you mean, you mined your way here from minecraft.

  • if you survive the 2012 phenomanon, you will wish you remembered the details of this vid.

  • @bae313 most important comment on this whole page. if the world ended and the survivors of the previous world had no knowledge of this kind of thing they would not survive. the resources left over from the previous world would diminish quickly ammunition food and materials would disappear within a few decades. I would totally start a community and just jump straight to sword and blade making. Skip the guns unless we learn how to make black powder.

  • @vulkein black powder can be made from 3 relatively easy to find or produce elements.

  • @bae313 well good luck making bullets that will work with modern day weapons.

  • I would like to know what all you would need for this procedure/ the equipment?

  • Where do u guys get the charcoal u guys are using from

  • Any chance on a link to a better diagram of the furnace you made for this? And what did you make the top part of the stack out of?

  • If you layer in a copper oxide would you get an alloy or would you get copper speckled throughout?

  • @mandyNdave You would simply contaminate the steel with copper, which is not desireable. It can either embrittle or soften steel, neither of which is something you want in a blade of any kind.

  • @tidewaterforge How exactaly did you make the forge, and how much would a block of that home made tamahagane go for? i would imagine somewhere around a grand or so. Give or take a few bucks.

  • @tidewaterforge How exactly did you make the forge, and how much would a block of that home made tamahagane go for? i would imagine somewhere around a grand or so. Give or take a few bucks.

  • needs more iron sand

  • lol I'd never think smelting, smithing, casting etc. could be so interresting.

  • thank you for the vid. thinkin of makeing forging a new hobby and this looks to be like somthing i'd have to try

  • This was beautiful, I'd love to attend something like this. How small an a furnace like this be scaled down?

  • @l3reak

    If you're anywhere near Baltimore, this technique along with a couple others for steelmaking will be demonstrated at Baltimore Knife & Sword in late march. They have info on their webpage.

  • @tidewaterforge do you have to be 18 to attend them?

  • Chuck Norris could pick that up.

  • - Continued,

    How in nature here in my location could I find the necessary sand to begin this process? I want to go about this all natural, but obviously I dont have a mine to enter to gather iron sand. I have read other post before asking this question, but wonder if my geographical location would become a problem for me to maybe do this on my own. "I have all the will", but need a way!

  • @CodyOebel

    I'm not aware of any good, natural sources of iron ore in Texas. The easiest way for you to start is to find a pottery store that sells Hematite - they use it as a glaze - it's just iron oxide, which is all the iron sand really is, just different amounts of Fe and O. Good luck.

  • @CodyOebel If you're near any creeks you can pan for it just like for gold. Its the heaviest thing in the sand so you have to dig deep around rocks and stuff...pan it and the black stuff that's last to pour out has a lot of iron in it. Its everywhere. Supposedly its from space dust.

  • This makes me want to build a furnace next to my home made forge :). Thanks for the video and team of experts taking their time to put together this project. I really enjoyed watching it, and took a great deal of education from it. On hand sight, I personally want to make my own carbon steel for a true neo tribal metal smithing project. Ive been making 5160 knives with no power tools, but want to take it a step further.

    I live in San Antonio, Texas. It's clay mostly here. How in - continued

  • I really like this video I will definitely be talking with you. I just posted a hand forged 5160 bowie in which I made all by hand and no power tools. (I follow the neo-tribal metal smith style of blade smithing), and how to make my own steel follows this catagory.

    Check my video if any of you want to see me hacking a 2x4 in half with the hammer forged bowie I made, and then I shave my leg with it.

  • @tidewaterforge Ya, of course - the way of making steel is approximately the same - except - japanese makers - they make best swords in the world and best razors in the world - and can you make same quality steel of this raw steel? I daubt..

  • @radiantrey

    The Japanese, of course, have been doing this a lot longer. There are US makers who can match that quality - I'm not one of them, but some of the guys in this video are. This is all a learning process, for everyone.

  • @radiantrey A japanese blade or katana,isn't forged once, but many times. it is constantly forged, folded and reforged. So he could, he just needs to constantly re-forge, fold and add to the initial blade.

  • @radiantrey these steels are obtained after refining dude. this stack is awesome.of course afterwards these awesome guys can decide to make another furnace for further refining and composition re-adjustment

  • @radiantrey Can you spell correctly? I doubt it.

  • @bobjoemagee Me too! :)

  • Tidewater

    HUGE Thanks for this post ! it was awesome to see this technique being used !

    Could you keep running the furnace for days ?. Or I guess until the clay gets consumed or broken down,

    You southern boys sure know the tricks, :)

    Thank you again.

    I am going to have my 13yo grandson watch this video,I am sure he will find it as fascinating as I did,

  • @EarlRausch

    The larger the furnace, the longer it may be run. For the backyard smelter, it's pretty much an all-day process. At some point the furnace usually breaks down, you run out of charcoal or ore, or you just get tired of feeding it.

  • How much Magnetite was used?

    This is just my guess, but It seems to me that if it was around 95% iron, and the bloom was around 65 lbs, assuming there was quite a bit lost for some reason or another, is 80 lbs anywhere close?

  • @MizuPsi Yield from any charcoal smelter tops out about 50% on a good day. Also, there was less than 50 pounds of actual finished metal at the end of it, so I would guess that between 100-120 pounds of ore was used that day.

  • @tidewaterforge Thanks. It seems like this is pretty expensive then, though I only spent 10 minutes in a search for a source, it was $10 per 5lb bag.

    Another question: Are you able to add alloying agents like Silicon or Nickel using this process?

  • @MizuPsi This is not a cheap way to make steel. And yes, one could alloy it, but the whole point is to create a clean, alloy-free material that resembles as closely as possible the ancient stuff. Alloy steel is readily available for cheap from a multitude of sources.

  • @tidewaterforge so you guys placed Iron in the tube between several layers of the fuel?

  • @uscorg Fill the furnace up with charcoal first, get it up to operating temperature, then as the charcoal starts being consumed, layer in ore, then charcoal, then more ore, etc., for the duration of the smelt.

  • @tidewaterforge so you guys placed Iron in the tube between several layers of the fuel?

  • Comment removed

  • Thanks

    

  • Isn't the furnace called a copula furnace?

  • where you can find iron sand?

  • @RockingOrange11 Any iron mine, some beaches and rivers downstream from large magnetite deposits, or occasionally pre-packaged (hematite glaze, for pottery).

  • Is it possible to make a furnace which you do not need to destroy at the end?

    great video, that is some cool stuff... hot... ehhh...it's just awesome, how about that.

  • @pyrea17 Possible, but not very practical. Several of us have experimented with that - most of the bricks above the hot zone are re-usable, so it's not that bad.

  • so only what to do is trow iron sand in it and you get a big bar of steel?

  • @RockingOrange11 Clearly you've not really watched the video - layering in iron ore with charcoal results in a "bloom" of high carbon material, which then needs to be consolidated into bar form before any forging can be done.

  • I enjoyed this video and recommended it to my students when studying the Blast Furnace at GCSE. (UK 14 to 16) You seem to be a group of erudite enthusiasts and I suspect archaeoligists. Do you have by chance a good video clip of a more modern Blast furnace

  • @mrikerrigan I think most of us might consider the term "experimental archaeologist" appropriate, though we do have one full time member of our group in that field in east Tennessee. The rest of us simply have a passion for old material, and learning how to make it is the only way to replicate the character and chemistry of ancient examples.

  • what sort f bricks are used to build the furnice ?

  • @al3e2x19 Standard hard fire bricks.

  • You got some dirty handy boy

  • Hey guys, thanks for a great video.

  • do you have any publications showing how to do this exactly?

  • This is awesome!

  • lol but when they make a sowerd they do fold the steel a lot

  • @Armstrong202 Yes, steel made this way needs to be folded and cleaned many times before it's suitable for making any blade with. As Dr. Blue says in the video, it creates the patterns, but they are a byproduct of the steel-making process.

  • @tidewaterforge How do you clean it?

  • @pyrea17 "cleaning" in this case, by folding up the raw material over and over - the non-iron components will work themselves out of the material, leaving steel with some silica, not unlike wrought iron, but hardenable.

  • So you just put Dirt+charcol and so on until you get the bloom? still dont get it! :P

  • @SDKsa1 "Dirt" in this case being iron ore.

  • Did You use Iron Sand, or something else cause i am very intrested in making Steel to make Knives.

  • @RedGhost1990 Any iron ore may be used - sand, magnetite, hematite, as long as the iron component is above 50% this process will work pretty well.

  • this is really great work! 

  • great vid i have a question. what do you do different to get steel out the bottom in stead of iron .

  • @jackdog20 As Dr. Blue states, it's time at temperature.  That can be manipulated by furnace geometry, stack height, rate of burn, and overall internal temperature.

  • I'm wondering where he sourced out the hematite? 

  • @age54321 This smelt used crushed Taconite pellets, which are mostly pure magnetite with a little clay. Hematite can also be used, and is available at pottery supply - they use it as a red glaze. But not in this video.

  • most beautiful thing i have seen so far involving fire

  • Amazing. Great video guys.

  • totally kick-ass!!!! i always wanted to know how steel was extracted. great upload mate.

  • hey i resemble that remark

    

  • Good job, well, where's the sword, you'all been drink'n?

  • @butkatrello Dr. Blue took the material back to Minnesota with him, I'm not sure what they did with this particular bloom.

  • Hello, Tide Water Forge. I have a question....due to my lack of knowledge of minerals and such.

    What charcoal are you using ? What type of charcoal contains most iron?

    What is hematite and Fe304 ? And isn't hematite Fe203 ?

    And last how do you clean the steel mold of the impurities, like glass and charcoal left overs ?

    What's that powder between the charcoal layers in the furnace?

    Thank you for the nice vid. I'm sorry if my questions are kinda stupid, I'm just an amateur blacksmith.

  • @xxColtyxx That's a lot of question in one post.

    The ore (hematite, magnetite, etc.) is what contains the iron. To smelt it is to remove the oxygen and some of the other impurities in the fire by burning charcoal. We all just use regular "lump charcoal", not briquettes.

    Purification comes by folding the material several times to remove silica, charcoal, and to even out the carbon content. This is what gives the stell its layers, but that's just part of the cleaning process.

  • look at them red neck necks having fun

  • @noir0222 Yep, except there are 3 Ph.D's in that crowd, and several Masters holders, who simply enjoy experimental archaeology and don't feel the need to overdress for the event. ;)

  • @tidewaterforge you should make a sword and then sell it on you tube or something like that but it does look like fun

  • @tidewaterforge

    Nice

  • @tidewaterforge

    LOL, noir got owned. May I ask what university???

  • @tidewaterforge hmmm 3 Ph.D's and several masters, im guessing the person who asked "is it still molten in the middle?" probly isnt one of them LOL

  • @tidewaterforge Doesnt mean they arnt RedNecks though does it? lol neway just messin. =p

  • @tidewaterforge Rednecks can be educated. You can do a lot of reading in the quiet of the country. This was a great video. Learning is so damn fun.

  • @noir0222 PHD in metalurgy? There's a bachelors and masters program in metal smithing down in southern illinois. Do you think it'd be more worthwhile to undertake this program, or to become an apprentice? This is a serious question.

  • @Cstrife234 having a katana is always cool

  • @nivenheim I think I've said it before, but you can use the red hematite sold at pottery supply for glaze as an ore - it works fine. Check out Don Fogg's bladesmithing forum for more on education, books, and a great community involved in this sort of stuff.

  • @nivenheim Only if you clean and seperate the ore from everything else. Yes, the red comes from hematite, but that isn't the only thing in it - you want as pure a product going in as you can, or else you'll just end up with a bunch of slag as the non-iron component of your dirt melts into glass. Excessive slag is bad, too, because it scavanges some of your iron away from the bloom. I would look for a more refined product to start with, or find a way to refine the iron in your material.

  • That was very interesting, thank you.

  • how does this make steel? isn't this basically an iron bloom?

  • @stupidnamenoonecares

    If you listen to Dr. Blue in the video, it's a function of the time at temperature. By making the stack taller than a traditional viking or roman stack furnace, it allows carbon to enter the material as it percolates downward, creating steel vs. iron. Yes, it's in bloom form, but it's already carburized and hardenable.

  • i listened! :D i listed about 5 times actually, he didn't say it was taller, he said it was different.

    but your answer fills in the blanks fine. so thanks for that. it seems to me your walking a fine line between making steel and pig iron. would that be why i've seen so many vids of japanese smiths overheating their blades which would decarburise the steel somewhat?

    anyway thanks for the upload, it's really interesting stuff. :)

  • scratch that last bit on decarburising steel. doesn't work like that...

  • nice work.

  • like the Red Ballons, designed to make us feel good. Thank you.

  • I read that the Japanese traditionally used magnetite.. the "black sand" that you can pan out of river sand. Gold panners know what it is. If you put some dirt on a paper and move a magnet around underneath the paper, the magnetite will link up into hairlike projections that move with the magnet. Might as well get rid of as much of the dross as possible before burning up all that good charcoal. You could harvest a lot of magnetite with a magnet.

  • Indeed, the ore used in this clip was magnetite, though not from the beds of Japanese rivers... but chemically very much the same. I prefer it, because there is less oxygen bound to the the iron than hematite or any other -ite's, but the end product is as much a function of how the furnace is run, as the starting ore of choice

  • what type of bricks are those?

  • High-temperature bricks - usually made of silica, a little cement, and some insulator. I've made them using vermiculite mixed with white sand and a bit of portland.

  • ok, i am going to try so explain this using the best of my knowledge. Dirt is full of silica, carbon, and different metal oxides or as it is commonly called rust. as everything is heated valence electrons become very excited and their kinetic energy approaches levels high enough to break their bonds and in this state oxygen bonds with carbon so the iron oxide reduces back to iron more or less and any iron ore also joins the bloom and silicates coalesce into glass

  • is there any special kind of dirt needed to do this?

  • "dirt", in this case, is iron ore... magnetite, hematite, or in plain english, rust.

  • be carefull of coal dust.

  • its charcoal.

  • whats the powder you speak of?

  • iron sand i guess

  • what did you use for an air source with those 3 tubes on he sides?

  • Is that just regular charcoal i can buy for like a grill?

  • pretty much ya.

  • Thankyou, is that all that is used to make the steel? I have no idea how this works, thanks

  • just think of it as combining iron powder with charcoal in a furnace. the charcoal holds carbon and the iron ore that is usually found in japan holds less chemicals like sulfur and phospherus which makes steel brittle. this steal is called tamahagane. it is what they originally used to make samurai katana in japan. most katana today are not made from tamahagane cause its expensive and hard to make.

  • no its like if you make a fire and you see all the coals of the burned wood you know the little glowing chunks you just spread those out and let them cool and go out and put them in safe place (they spontaneously combust). i'm not that great at explaining this look at purgatoryironworks videos.

  • how much does the magnetite cost per pound, and how much did north shore require you to purchase(ie was there a minimum purchase), is there any particular charcoal you prefer? both for furnace and forging

    thanks

  • Hey great video!

    Do you have plans of how to build a furnace like this, I would realy like to build one.

  • Why are they so excited about it? What are they gonna do with it? Is it worth money or what?

  • Knife makers use it to make blades.

  • It is the only way to get steel of the same chemistry and character as the authentic Japanese steel used in Katana. You can't simply buy the stuff... if you want it, you have to make it.

  • This is a cool video The vikings use to use peat to make weapons they would burn it and they would be left with the iron

  • ??... no, the Viking stack furnace for ironmaking was very similar to this, but a shorter tube. Weapons were then forged like anything else, in a charcoal fire. I reccomend reading William Short's book, Viking Weapons & Compat Techniques for more information on that.

  • I guess Rosie O'donell never saw these guys use fire to melt steel...?

  • LOL yeah good one. What a retarded woman. Can't stand her.

  • For those wondering what the "dirt" or powder is, it is eventually Fe3O4 (Black iron oxide).

  • same stuff in hand warmers

  • what does the powder start out as? from what i understand from his illustrations, it is the iron powder that will eventually drip into a large chunk at the bottom. Is that right?

    I have no understanding of this process so if my question seems uninformed well it is... thanks for any help that can be offered.

  • In this case, it is iron magnetite from Minnesota... very pure, about 95% pure ore. The iron sand used in Japan is basically the same stuff, but instead of being mined from underground it is weathered from the hills and ends up as deposits in sand in the rivers. At the end of the day it's all chemically the same, Magnetite... just variations on what it's mixed up with.

  • great vids man! you inspire me to work for a living as a blacksmith is it possible to? haven't seen any schools that accept blacksmithing as a profession in today's Modern Society.

  • I think you have to be a apprentice .
