That's because magnetite has a much higher yield than hematite, and they ran a large amount of the black sand thru it between feedings. It boggles my mind how many hobbyists out there get even those most basic details right ... not tall enough, insufficient airflow, insufficient fuel, insufficient ore, etc. There are so many vids out there with the resulting bloom being tiny, uselessly impure and overfull of trapped slag, etc. It was refreshing to see someone do such a relatively good job.
Wow thats the way to do it ...I see so many of these videos where people just don't value what theyre making and the resources going into them but you nailed it...a beautiful bloom and a huge homogenous piece of iron...very very cool Well done guys
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
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
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 😅
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!
@@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.
Now it makes sense! my mom had this “beach”-saying: “Once you go black, you will never go back”. She is right afterall! Black is much harder, tougher, and can withstand a multi-hour “warm-up” - and still keep on hammering and smashing the bloom! For hours!!
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!
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.
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.
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
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
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. ...
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
Great video! Thanks for sharing! Subscribing to see what you're going to forge with it! (Hopefully a hammer, some tongs and chisel - i.e bootstrapping blacksmithing from scratch)
@@jakobhalskov would love to see a video of you refining it into usable pieces, not just here's the ingot we made out of the bloom, let's make so and so
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.
Man literally made a minecraft grass block

That was an amazing oven, great execution, one of the best home made smelters I've seen. That harvest was impressive.

With the ancestors, there would have been more singing, beer, and mead.
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
At 07:03 onwards I enjoyed the dance😅.

Love how you're doing like next level blacksmithing in a suburban garden lol
Actually this form of blacksmithing has been used in Denmark for at least 1300 years. Vikings don't ya know...
This is what happens when there's no Renaissance Fair or cosplay event for these guys to attend.
Removing the lawn to place it back later at first had me convinced this must be Germany. :D
Hah, close! Denmark just north of Germany :)
@@jakobhalskov For now ....

Cool, we wish you the very best luck with the process and journey this is! :)
The trick is it has to be a charcoal forge. In a gas forge there's nothing to add carbon to the iron.
@@anoncommenter6726 thanks for the info! It's been a long while since I've had a chance to try it, but I'll save this comment for next time
@@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.
@@williamkao5747 So it was designed as a gas forge, but I did this by burning charcoal inside it and stuck a blower in the torch hole
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
Yeah, we got great soil here in Denmark - more than 60% of the country is used for farming and growing crops.
Wow! Everything about this was beautiful, from the iron working to the scenery.
You make me want to visit Denmark.
enough iron to potentially make 15 swords
This is very cool that you did this with just some friends in your yard.

@@amogusenjoyerYeah the magnetic separation prior to smelting was absolutely genius. Took away a huge amount of the slag before it even melted
From where did you get the bog ore?
From a plowed field in Midtjylland, Denmark :)

The playground at my elementary school had some sort of black sand playlots. We would drag magnets thru it to collect the iron.
Ah that sounds like fun! Here in Denmark I only know of one place where this black sand can be found.
When you threw the sawdust in during the preheat 😂👍.
Definitely sharing this one. Great video. Subbed

good ole' black sand, always with its high purity benefit!
Crazy amount of effort and energy being spent back then. We owe so much to technology
