Dear John. As a metallurgy engineer that handles ore into kiln, I have the following advice: I suggest you start with smaller fire and continuously build it up to increase the temperature, but it is important to keep a calm fire after starting it. Drying the ore slowly is the key to a nice and ready charge for the coal. Once you start adding coal (after 3-4 hours of drying the ore), I suggest you try making breaks while blowing, to let the coal and the charge cook well, like cooking a steak at a low temperature, because too much air will oxidize the iron earlier before it reaches a temperature near liquid phase before smelting, so that could be the problem why you are still getting small prills. Try making small pellets of 1 cubic centimeter of the ore. Burning the iron ore right from the start will cause the iron to pop and form into smaller prills into the slag. Also lime is added in liquid metal only (from my experience so far) Hope this helps!

좋은 정보 감사합니다

I tested roasting the ore, using lime flux (shells) and recycling slag in 3 separate smelts. Roasting the ore improved the yield about 2 times though this might have been due to decreasing the volume and effectively increasing the concentration of the ore. Adding lime (snail shells) ruined the smelt and produced next to no iron. This may be due to the ore already being basic and chemistry and the lime made it so basic that the slag won't flow. Sand (an acid flux) or old slag might make a better flux for this type of ore, lime might be better used to flux iron sand (acidic due to the silica content). Finally, I tested re-smelting the slag from previous smelts (not the slag from the lime smelt). The result was about half the iron came out compared to fresh ore, which suggests that slag should be smelted again to recover any iron not obtained during the first smelt if fresh ore is hard to come by. Thanks.

The chemical used to lower the melting point of the slag (unwanted materials, also called dross) is calcium oxide. Wood ashes contain calcium oxide, as does pre-burnt shells, and limestone that has been baked into quicklime has the most calcium oxide. Since he's in an area with no limestone, he only has ashes and snail shells to work with. The failure may have been due to the fact the shells were merely crushed, and not pre-baked, as happened in a previous experiment (turning snail shells into the calcium oxide / hydroxide needed for making cement) several years ago. Or it simply could have been too much calcium oxide, because yes, sometimes too much of a good thing is actually a bad thing in the end.

Then fully dry the pellets and load the entire furnace (preheated) with them. The main purpose of pellets is to make the contact between components as close as possible while the shape guarantees there is sufficient air flow throughout the whole furnace.

On the note of air flow, getting a consistent input flow could dramatically increase the heat and flow rate of the furnace which would let the iron flow together more readily. Replacing the current rope drill power source with a rotary power supply (something like a rope belt and two differently-sized clay wheels, with a handle on the larger wheel to convert slow human-supplied rotation into a fast fan speed) might allow for consistent blowing speed without taking a ton of effort to build and maintain. Hopefully. I don't know for certain how tough lawyer cane is, or how brittle his fired clay is, so I can't say for certain what's the best solution.

Impressive how much the yield amount changes by simply firing the ore beforehand. Would it be possible to use some of that iron to perhaps make a primitive flint and steel? It would be like a cool little upgrade from the friction method and hopefully easier to use/maintain. Great content as always!

All this experimenting with iron ore and smelting is so fascinating, looks like you made some great breakthroughs this video!

I'm a smith, I've done one modern-ish smelt. I can't get enough of this journey you're undertaking. Re-smelting slag is absolutely worth it in an ore-poor situation. Silica sand is an excellent flux for bloomery smelting. Is there no other source of ore in your locale? I'm pretty sure with the process you've already developed and a more sizeable quantity of ore (and higher grade ore) you'd be getting much more iron. Also, I find myself wondering about the primitive technology form of a basic magnet... something to help locate and purify ore.

I was thinking a magnet would be useful as well, but unfortunately with a primitive level of technology there's no way (that I know of) to make one. Back in ancient times the only way to get a magnet would be to find a naturally-occurring lodestone.

Short of a permanent magnet, the only other source of a magnetic field would be an electric current. At the very least 2 metals that are of differing electronegativity would be needed to create a galvanic cell. This is territory where mass production starts changing from a good idea and into a necessity.

The one and only true primitive technology channel out there, and I'm so hyped every time there's a new video!

It's amazing to see the progress you've made from the tiniest of nuggets to this. You have perfected your approach and the results are very nice.

I appreciate that you showed the Lime one after it caused a failure. It's neat to see the methods that don't work. Both helpful to teach the chemistry and also shows the authenticity that it doesn't always work the way you hope.

So cool watching him get more efficient with iron yield experience. Everyone seems to talk about making knives or hatchets or something, but after so many iron videos, I'd be curious to see more experiments with food as well as pottery... perhaps a potter's wheel.

WOW, this is where scaling up the production would really help and its why ancient people build settlements. If there was a person whose job it was to collect the ore, one to roast the ore, other 2 to produce enough charcoal, another one to smelt it, and another one to break apart the slag etc. you could get a lot of iron out of this. Incredible stuff!

my favourite parts about these recent videos is seeing how the very pragmatic design choices that you make for your tools (pots, furnaces, huts) eventually lead to a design that is present in the modern day. Like, "oh, I need better firing, so I need a taller furnace. Oh, now I can't reach in, I need a door' suddenly you have the modern furnace shape

love how the flame turns pink during the smelting

A couple proposed modifications: adding the water soluble parts of wood ash (potassium and sodium carbonates) to the ore to act as flux, then roasting the alkali+ore in a clay pot, so it doesn't get mixed in with the calcium oxide/carbonate from the wood ash. Potassium and sodium silicates melt much more easily than calcium silicates.

Considering the considerable (hehe) high amount of iron in the "leftovers" is it possible that the current oven design can not produce enough heat? Or will excess heat possibly even hinder the smelting process? I love your videos! The combination of interesting, educational, satisfaction and chill vibes! It's amazing!
