About This Video:
I took a brittle, high carbon/iron alloy (cast iron) made from local ore and used a decarburization method to reduce it's carbon content making it malleable and forged it flat by hammering.
Rather than producing a single bloom of soft iron in my furnaces, as was done in most of history, I tend to produce cast iron prills from the ore. Cast iron is iron that has a very high carbon content. Its good properties are that it's very hard and has a low melting point. The drawback is that it's relatively brittle compared to regular iron. So I set about trying to find a method for reducing its carbon content.
In this video I smelted local ore (iron bacteria) and obtained cast iron prills. I then tried melting it in a small crucible to obtain a solid ingot to begin the experiment. This gave a poor result though with an incomplete melt.
Next I tried rusting the prills first with the intent of creating iron oxide (rust ) in the iron so that the next melt would combine the materials in an exothermic reaction that would burn the carbon out. In the past, rusty iron was added to cast iron to decarburize it (wet puddling/pig boiling). But this also gave poor results.
Finally, I did away with the mold and simply melted the iron prills by dropping them into the forge in front of the hot air blast of the forge. The reasoning was that the high oxygen would burn out the carbon from the metal. This caused them to melt together to form an ingot. After a few attempts I took one of the ingots and hammered it while still white to yellow hot and hammered it with a stone. The ingot was able to be flattened as it had become malleable. This was the result I wanted.
This method of decarburization (melting cast iron in a open hearth to make it malleable) was used throughout history at different times. In ancient China it was known as "stir fried steel/ 炒钢" and in the west known as the "Osmond process". I also read that in India, cast iron ingots from the crucible were brought to a temperature just below melting point before becoming forgeable.
In future experiments I hope to use this technique to decarburize iron ingots to make into forged metal tools as opposed to the cast knife I made in a previous video.

About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials. To find specific videos, visit my playlist tab for building videos focused on pyrotechnology, shelter, weapons, food & agriculture, tools & machines, and weaving & fiber.

I think I figured out how to turn the brittle cast iron I've been producing into malleable iron that can be forged flat. When ever I smelt local ores it always produces cast iron prills rather than softer blooms of low carbon iron as one would expect from the bloomery process. I believe this because the prills are very hard, but when struck hard enough they shatter rather than flatten. Cast iron is iron that has a high carbon content (when arranged by carbon content: Cast iron>Steel>iron). Cast iron has a lower melting point and is harder compared to regular iron. But it is more brittle so it's nearly impossible to forge. So I figured out how to decarburize it after some experiments. First I tried making an ingot to work on but it didn't cast properly. Then I tried rusting the iron to oxidize the metal before melting so it would decarburize the cast iron during the melt (similar to the "wet puddling" process in metallurgy). But this gave an incomplete melt also. The method that finally worked was simply melting the cast iron in front of the air blast till the carbon burnt out in the oxygen rich zone of the forge. This caused the cast iron prills to melt together in a single blob that I then was able to hammer flat while yellow hot. This method is similar to the "stir fried steel/ 炒钢" process in ancient China or the "Osmond process" in Europe. It's done where ever cast iron needs to be converted to a lower carbon to be forged. I've seen videos about carburizing iron on youtube but none about decarburizing cast iron.

Have you tried using higher furnace, like the 'smokers' or dymarki that were used in central Europe around 9-10th century? It produces less slag, and something more akin to usable ingots. Truth be told - you'll need a large load of ore to make it worthwhile.

Maybe so, however getting scraps of iron after years of work is one thing, being able to ensure you can mass-produce iron and improve methods to ensure a larger volume that makes it possible to not require months of work is another thing entirely. Most other innovations would probably require more smelting than prior.

Okay so a few things: 1) I think it could help to cover the sides of the open heart forge a bit. It would force the flames to go into the iron and not out the sides 2) To make the process less work intensive you can first heat up the iron in a ceramic dish, in a cross-draft furnace. It would get it up the first few hundred degrees and only the rest would have to be done by hand-pumping the air into the forge. 3) you absolutely need a roughly flat, stable and level working space. It can be a large rock, stabilised to the floor with clay 4) to fuse multiple pieces of iron into a larger chunk, hammer each piece into as flat a shap as you can, heat them up, lay one on another and... Bang! 5) a good tool for then working with the iron is a wedge-shaped stone. So far you have a stone hammer, so you can bend the flat iron over an edge. Once you do that, you're gonna need a wedge to hold the 90° bent piece in place. For this you need a wedge with an internal angle of about 70° to 50°. This will let you bend it further amd then close the bent piece on itself, thus making the iron plate more uniform.

One way to adjust the carbon content in the iron is to raise the height of the air tube. This keeps the iron bloom at a lower temp and prevents any new carbon from the charcoal from getting added in while allowing for more to eventually collect at the bottom.

Yeah even in the mid-late medieval, smelting, working and treating metals for use was an absolute time sink of a job. With blast furnaces and armies of generationally trained smiths a set of armour for a knight could be $500k+ in today's money. In the days of primordial man... Let's just say, if you knew how to smith, your life and knowledge was invaluable.

@@AMorphicTool That's why I find modern society's fascination with swords so irritating. Swords were expensive status symbols. Useful for self defense, but on a battlefield almost always relegated to sidearm status. Most fantasy novels that feature a medieval theme border on unreadable for me because of how dumb the descriptions of the battles are, and how ridiculous the armor everyone is wearing is (boiled leather abounds). I wish fantasy authors would do more rigorous research. More than that though, I wish they'd _finish their damn series before they die._

A blacksmiths take on it: If you remelt that 'bloom' as it could roughly considered, you'll add more carbon to it because you're using charcoal. If you want to get the impurities out without much carbon addition, you should stick to about a strong orange color or cooler. If your bloom is yellow, you're entering the caution zone, and it you start seeing white, you're too hot. Keep it highere in the fire for reheating, I think the issue you were initially running into was being too close to the tuyere, causing the melt to bounce between oxidation and burning, to carbonizing as you pumped air in and out. Try lowering your RPM so to speak as you get closer to the melting temperature on the next run and see how that goes.

There's a couple interesting things about smelting that you might want to look at for future working. One thing is that you're not aiming to melt the iron, but rather to melt the NOT-iron, and for that limestone flux would be VERY useful. (maybe use the shells?) The other is that you want to start with VERY dry ore, so baking the ore powder even more might be worth while. It also seems that, from what I can tell, you actually want less charcoal than ore- I think a lot of why you're getting cast iron is because you're basically smelting in a high carbon environment inside the charcoal. Maybe making a tiny thin smeltery chimney could help, or just spending the time to collect significantly more ore.

This is less similar to the Osmond process and closer to the Lancashire Hearth process! All these old European iron processes are extremely similar though. You may find that this is a high carbon steel ~1%. Good for tool making, but can be difficult to work with, it's spongy nature means it will be more prone to crack than a lower carbon alloy. To get a very malleable "wrought iron" product with lower carbon, the droplets of iron need to be bathed in slag (usually silica based, with lime and iron added). With the Osmond process, the drops fall onto a collecting rod and are pulled from the furnace that way. In the Lancashire hearth process, droplets fall into a mass bathed in liquid slag at the bottom of the hearth and the bloom was pulled out when it had gotten big enough. Fantastic video! Can't wait to see what you make next

I had the same problem with melting scraps of indium in laboratory:^) Use some flux to save metal from oxidation (I used rosin, but it won't applicable in your case, maybe you should try to use CaCO3 as a flux (chalk or shell covers or marble or any other cedimentary rock like limestone).
