great quality video. as your friends sat around watching you guys I wondered how it would have been the same so many years ago with your ancestors. neat video 10/10

I've been trying to make my own iron on and off (mostly off) for a little over a year now, most of that time spent gathering ore. A few things I tried to smelt it didn't work, but yesterday I had a very minor success using my diy gas forge as a bloom furnace. Most of the magnetite sand didn't smelt at all, but some worked out well and coalesced into a couple small melty looking pieces. This should help a lot in improving my process, thanks
Not surprising the magnetically separated material produced a giant bloom it had to be hundreds of times purer than that bog ore. Also multiple tappings moved most of the slag left out and away. Pretty genius.
I'm actually surprised about how much stuff there is in the sand. I know it's sand but I thought the iron content would be much higher! Makes sense now that I actually think about it though, it's sand not powdered iron 😅
I have to say...your soil is magnificent. Here in North Texas, our ground is mostly rock and infertile and must be heavily modified to make things grow
@@jakobhalskov Super cool, and really you couldnt have done it better I dont think, your collection and separation really gave you a good volume of material, and for Me, really gives a good idea of what a more ironcentric village might have produced way back when at the beginning of time. Really cool, and I bet all your friends who helped will Never forget that.
You can easily make a magnetic drum separator to take the magnetite out. That way you can process more material, and make multiple runs, reducing the extraneous matter.
Hello! I just stumbled onto your video and I am really glad that I did! Your skills and resourcefulness are amazing! Thank you for sharing that process with us! I subscribed. All the best!
I didn't quite understand why you were doing it this way to begin with until you broke the first one open, and then I got it immediately. Imagine in the old days when they first figured out such things by accident.
Hot DAMN that was a massive iron bloom! Man, I cannot wait to make my own iron again. Did it twice with my friends back in school, alas, I ended up getting nothing from the smelts. Ack!
When I was a kid I would use the 2 Tupperware bowls one had the strong magnet the other had the surface area I would rub on sand when you wanted to remove the filings lift sealed bowl and place the surface bowl in the container. My uncle worked for Lockheed so got me a high tech magnet well high tech for the 80s.
Where I live black sand consists of oil....was the wheel barrow just for video ? Couldn't help but notice one bag of charcoal in it. Coulda just carried that eh ?
Used a strong industrial magnet i borrowed from a friend, think you could use one of those they use for magnet fishing. As for the sand, found it on the beaches of north western Jutland. I dont know how common magnetite sand is on other beaches
I love how much effort, time and money goes into this, because it is simply cool. It would be much easier to melt down some scrap iron. But what's the fun in that? :D
Magnetite is thought to be found only as large crystals, but those are extremely rare. Instead magnetite is found as banded iron formations or in iron sand. In igneous rocks the grains of magnetite are very scarce and minuscule but are concentrated into sand due to weathering.
I don't know who you are or what organization you are with but that was a very awesome video I have one bit of advice though try surrounding the furnace and a layer of cob to try and contain more heat in the end it still worked so that just might help in the future
I thought best practice was to mix limestone with the iron sand to assist slag formation and runoff ? BTW your plinth probably should have been underlaid by 4 small I beans ... it wouldnt have tilted the way it did when you harvested the bloom (6:50).
Thanks Ron, good to hear from you - I have a dream of getting into designing and casting 5-10kg bronze bell one day. Currently working on a bigger electrical furnace for burning out plaster molds.
@@jakobhalskov So far I have made a 6 inch brass bell but I make large aluminum bells I mix zinc with the aluminum and the ring is much better...I plan to do an 8 inch bell of brass soon. I use medium fine sand from local farm store and bentonite pond clay. for the molds
@@jakobhalskov Hi Jacob I buy real bells from antique stores or plastic ones that look enough like a bell. I have a bottom wood box and fill it with sand. I pack the false bell with sand like making a sand castle. I put it in center. of bottom sand filled box. Then I press the sand tight around rim of the false bell real tight...Then I use baby powder and sift around that and also the bell pattern (false bell) At top of false bell I use a cut off pipe and put it in the middle of top of false bell...My cope box has angle iron pieces on all 4 corners so it will stay aligned. I put the top cope box over it and pack sand all around the outside of the false bell and pack tight all way yp to top pipe on the bell pattern....I take the pipe and swirl it a making a cone shape and then I pull it out... get a stiff clothe hanger wire and make little holes by sinking wire over bell pattern top. This will help wit releases of any gas trapped in the mold.I lift the top box off of the bottom and gently set it aside. I tap the false bell and lift it off which leaves a bell shaped core. Then sit the box down and the angle iron pieces slide down to the bottom with cope box...I fillaround the outside with sand to keep bottom from leaking.. Then I pour the bell. ...
Did you pan that black sand for gold before you melted it down? Now I know what to do with all the black sand I have left over from prospecting for gold. I have buckets of it I have saved.
We did not pan the sand for gold, but don't expect there to be any significant amount of gold in it, as we are in an area with very low gold occurrence and don't think the beach waves is able to concentrate the gold there should be precent. I'll give it a try next time im at that beach. With the concentrated black sand you need about 4 to 5 times as much sand than iron you expect to extract. And at least 10 kg to make a small bloom, you'll regret to make a 30 kg bloom as we did. Regards Sebastian
Nice last yield. How much does a bloom typically reduce in volume when fully compacted ? I have a lot of redly colored hill magnetite here. I find the idea of doing an old fashion coalpile and smelts rather tempting :)
if you fold it a few times it is not unlikely you are only left with 1/4 of the starting bloom. So make more than you think you need. The 1/3 loss is mostly in the first compaction. Sorry for the potential confusion. -Sebastian
@@jakobhalskov Life is learning by confusion, revision of detail is a step process. I appreciate both it and that you bother to add correction. Thanks :) I figure from observing scaling from impact working any mass manufactured iron/steel, there will be losses of mass at any process of compaction shaping. Carbon reduction, impurities etc. Thinking of it, it does sound much like the Bessimer... On mere ish assumption; How much stronger could a traditional poured steel cast anvil become, compared to one well forged in iron ?
A comment on the Bessimer process; the iron in a blommery dose not really melt. Though planning on doing a video on hearth fining iron, to reduce phosphorus and slag, maybe make some steel. With out promising anything. About the strength, using tensile strength as a proxy for strength/toughness/quality. As from the 2 articles I can find on strength of bloom/wrought iron. Bloom/wrought iron have a tensile strenght of 200-300 MPa. The samples was probably not heat treated, though the low C content is not allowing for much hardening. In comparison to 4140 alloy (common tool steel) have a tensile strength of 900-1500 MPa. after heat treatment. Not in any way a one to one comparison but might give a ballpark feeling of the difference, might be completely wrong. One "common" failure of old forged anvils is the horn and heel gets knocked off with sufficient abuse, because the anvil is forge welded together from multiple pieces. But there are also many anvils that have not broken in that way. -Sebastian
This is pretty damn cool, I might have tried making my own iron in the future but it really looks like doing this alone mighe not be a very smart idea lol. Possibly if a smaller scale is possible to make something that weighs only a few kilos, but you do need people around to prevent fire spread.
I tried doing something like this once for my birthday. spent a month preparing my back garden, had all the tools and stuff ready then just as i lit the fire i quickly found out my neighbour has ptsd of fire and smoke from an unfortunate car accident, so couldnt continue in good faith
You would risk making cast iron, which is unforgeable and it's not exactly easy to oxidise the carbon to make it into steel at home, but can be done. There is also the risk of introducing sulfur from the coal which isn't desirable. Charcoal burn fast and clean.
Think magnets to have a significant strength to do this is only know for a few hundreds year (i could be wrong).To my knowledge there have not been used magnetic separation of ore in a historical content.
@@jakobhalskov I mean magnetic rocks have been around as long as rock itself. I am sure our ancestors would have picked up magnetic rocks and thought "I wonder what would happen if I melt all this together".
That was an amazing oven, great execution, one of the best home made smelters I've seen. That harvest was impressive.

The last bloom was absolutely huge! 😯
Yeah, we did not expect to get such a big yield from the black sand!
What’s the purpose of the bloom?
@@styx62ga95 The bloom contains the refined iron and slag, and the bloom is compacted to further refine the iron

The trick is it has to be a charcoal forge. In a gas forge there's nothing to add carbon to the iron.

@@gamemeister27carbon is needed to reduce the iron oxide into iron, to do the same in gas stove you would need to burn hydrogen or carbon monoxide.

Estimation of how much all that charcoal cost?
We bought around 300 kilograms of charcoal at price around 2400 DKK ≈ 400 USD for four runs of iron extraction.
Would be worth portioning your melts to result in a specific size ending chunk of iron.
