The most impressive thing for me was the fact that you were able to sun dry the sand in Denmark :D. Nice job chaps

[@DioDCynic]

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

[@RovingPunster]

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.

[@joshschneider9766]

@@styx62ga95 the bloom is spongy impure iron. To get it to a useable state it's hammered into a rectangular billet, drawn out in length, folded in half, reheated, and drawn out again. Done carefully this results in useful material. If you ever see old time iron objects that look like they have a faint wood grain it's the result of that purification folding process.

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

[@jakobhalskov]

Cool, we wish you the very best luck with the process and journey this is! :)

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.

[@jakobhalskov]

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

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.

[@phillipsusi1791]

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]

It will be iron/carburized steel with slag mixed throughout. It will need to be worked hot to expel the slag and consolidate the metallic content.

[@phillipsusi1791]

@@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 ).

[@kovona]

@@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.

[@jakobhalskov]

Indeed! I will ask my brother, Sebastian, about the carbon content of the two blooms. Regarding the tuyere we had casted one of copper to be able to cool it well to prevent it from melting when exposed to the high temperatures within the oven.

[@MrWTPunk]

@@jakobhalskov Thank you! I still don't understand. Copper melt before steel pipe. And cooling it OK, but why would it be easyer to cool? Or... You are aiming historical accuracy and in this case copper is better than clay and steel pipe would be anachronic? Sorry that's a lot of questions

[@jakobhalskov]

@@MrWTPunk The idea is that when the tip of the tuyere gets heated, that heat energy can more easily be transferred to the outside at radiate away due to coppers ability to transfer heat (compared to steel for example). Regarding the carbon content; our feeling is that the black sand iron has a larger carbon content than the bog ore, but we still need to do a proper spark test to determine this.

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 :)

[@jakobhalskov]

From the raw bloom to forged into usable bars you lose about 1/3 in weight, a combination of slag and forge scale

[@jakobhalskov]

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

[@ogreunderbridge5204]

@@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 ?

[@jakobhalskov]

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

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.
