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
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 😅
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!
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!!
@@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.
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.
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
"It was known among local nobility that whoever was able to draw the sword from the stone will be the one true king" This is a fantastic demonstration of an iron age foundry For years I've been trying to explain and convince people that this is the reference of legend of how King Arthur drawing the sword from the stone. The process you used in beating the bloom into shape and finally into an object on the anvil, is called drawing, a term used for many centuries and still used today. Maybe unintentionally you have provided proof of concept that King of all Britons King Arthur once worked river stone or black sand to draw from it his sword and thereby proving his right to be king.
Lol so you're saying that before swords were even invented, random farmers and villagers had theorized a process of creating a weapon out of purified stone? You're saying nobody had ever made a sword before, but they had terminology for the smithing process? "Drawing" is only one step in smithing anyway. It's _possible_ that some people called smithing "drawing" but I'm pretty sure they mostly called it "smithing" or "forging" 🙄 It's nice to play around with ideas, but you said that you've been trying to convince people of your theory... Are you telling me you just made up this theory, assumed you were right about it, and now for years you've been attempting to rewrite history to make yourself look smart?
@@Leto_0 Firstly nincompoop This process developed over hundreds if not thousands of years through the bronze age making axes knives and such. The rest of your remark clearly shows you have never completed an apprentiship in the metal trades. The blast furnace was not invented until 1709 by Abraham Darby so how do you propose iron was wrought from stone? In fact what made Britain so attractive to the Romans was the tin and copper mining and the production of bronze on the island.
@@Leto_0 Duh! I didn't say Arthur invented the sword I have merely pointed out how words and expressions can be misconstrued by accademics in their retelling and interpretation of ancient tales (Bible being the prime example). The quote I use is from Mallory's "Mort de Arthur" so rather than some fanciful miracale of a ready made sword being pulled out of a boulder by a boy, wouldn't the more likely story be of an apprentice smith making a sword from ore to the final weapon. Clearly you have no background in the trade as a Smith is the tradesman, forging as in the heating source and drawing or wroughting as in the working of the metal with heat. The blast furnace wasn't invented until 1709 by Abraham Darby and until then all iron was drawn by hand or later with steam hammers wrought. The terms you were grasping for were "Drawing" and Wrought" as in "wrought iron" There is a term called forge welding where one uses the forge to weld two pieces together which paradoxically isn't actually welding. The Myths and Legends of King Arthur are not history I merely wish to see how a story can develope from it's origins. And so a Legend morphs into a myth.
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.
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.

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 ?
That was pretty cool, but what do you do with the bloom now? Am I correct that it is actually steel rather than iron due to having a high carbon content? So it needs to be folded in a forge and over an anvil to reduce the carbon content and other silicate impurities?
@@kovona If you get it completely molten, won't the slag and steel settle into different layers due to gravity and their different density? Like oil and water separating? Then you can just skim off the iron/steel? Is that what blast furnaces do? ( I really should know this seeing as my grandpa worked in a blast furnace all his life ).
@@phillipsusi1791 They did that with pig/cast iron, but cast iron has a lot of carbon in it which lowers the melting temperature (to about 1100-1200'C). The excess carbon also makes it more brittle and less malleable, and impossible to do forge work with. Wrought iron and steel has much less carbon in it, so the melting temperature is higher (above 1400'C), too high for the simple charcoal fueled furnaces of antiquity and middle-ages to melt completely. Since smiths couldn't reliably get the iron to melt, forging it to expel slag and consolidate the iron/steel was the next best thing. Note, there was also another process in which iron ore was first smelted and processed into cast iron to remove the slag, then the cast iron was remelted over and over again in a finery forge to burn off excess carbon and turn the cast iron into wrought iron. Later on, they expanded the process with the puddling furnace, where a pool of molten cast iron was stirred with iron rods to help carbon burn off. As carbon was reduced and the melting temperature of the iron increased, the solidifying iron stuck onto the rods and formed balls of refined wrought iron. This "puddled" wrought iron was a lot purer and had different properties to the old bloomery type wrought iron.
The big pieces you see falling off is part of the furnace walls and slag that is stuck to the bloom. But we did loose some iron that did not stick properly to the bloom, though that can be used in a future smelt.
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
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".
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
We did not pan any of the sand for gold, but don't think the conditions at the beach would concentrate gold in any significant amount. At 0:48 you can see the "gems", the brown is most likely garnets, green olive and clear and pink is quarts, but they are sub mm in size; regards Sebastian

Wrought iron and steel has much less carbon in it, so the melting temperature is higher (above 1400'C), too high for the simple charcoal fueled furnaces of antiquity and middle-ages to melt completely. Since smiths couldn't reliably get the iron to melt, forging it to expel slag and consolidate the iron/steel was the next best thing.
Note, there was also another process in which iron ore was first smelted and processed into cast iron to remove the slag, then the cast iron was remelted over and over again in a finery forge to burn off excess carbon and turn the cast iron into wrought iron. Later on, they expanded the process with the puddling furnace, where a pool of molten cast iron was stirred with iron rods to help carbon burn off. As carbon was reduced and the melting temperature of the iron increased, the solidifying iron stuck onto the rods and formed balls of refined wrought iron. This "puddled" wrought iron was a lot purer and had different properties to the old bloomery type wrought iron.
These guys really just went, "let's make some iron then went with it
Hello, do also this things. But with bought ore. No i want to search it. Germany is not so far away.
Where in Denmark you found it?
Do u lose any iron once u remove the lump from the oven? Seemed like some was lost but idk what I am looking at really
The big pieces you see falling off is part of the furnace walls and slag that is stuck to the bloom. But we did loose some iron that did not stick properly to the bloom, though that can be used in a future smelt.
Would have dug helping out on that project.
Why did you take out the blum so soon? To burn off impurities.
Well, didnt know i needed that, but everyday is a day for learning 🤟
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
We are just some young guys new to this and we are learning a lot from every time we try this. Thanks for the advise!
@primativetechnology - did they have magnets "back in the day"? I feel like this is a good way of getting a bloom if it fits the genre.
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".
Metal working is so beautiful
If you think about it the crafted metal meteors
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 :)
From the raw bloom to forged into usable bars you lose about 1/3 in weight, a combination of slag and forge scale
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.

@@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.

Did you pan any of the sand off to check for gold/gem content?
We did not pan any of the sand for gold, but don't think the conditions at the beach would concentrate gold in any significant amount. At 0:48 you can see the "gems", the brown is most likely garnets, green olive and clear and pink is quarts, but they are sub mm in size; regards Sebastian
i hope you good health for you and your husband. Your vidéos are so pleasant and are profs you are so courageous. You are real exemples !
Ever done in Denmark???
now make a hundred year old katana from that
It is actually the dream..!
Big iron glob. Wonderful
When are we going to see that metal being forged into some weird tool?
Quite soon! Today we worked some pieces of the bloom into more solid pieces of iron; the video of this will be released this week.
The real title should be “Made molten lava from sand on the beach!”
