Bravo and thank you for posting! I know its old- but as someone who is NOW getting into the curiosity of the refining craft- THANK YOU! Hopefully you folks post more! Thank you again and SUBSCRIBED
Thank you Emiliano, really appreciate you sharing your wisdom! Is it possible to create large billets if using a larger hearth furnace and more overall charges? I'm trying to work out how to create a large block of high carbon steel that can be hardened and precision machined. Forge welding smaller pieces was my first thought but decided it wouldn't be strong enough.
l'd like to understand and hear more of this in detail, so l can myself try to make steel. 10:45 "l know it is kind of non-answer" - that's what l hate to hear when someone says that. That means that teacher has failed to give every aspect of explanation to listener, what l'd have liked to hear. Because this is an european style furnace, then of course l'd want to know more about it.
they should be drinking beer and having more fun why doesn't the bloomery carbeurize the iron into steel? why does it need the second heating in the charcoal?
In the bloomery furnace all the carbon is used to 'reduce' (ie attract) the oxygen from the ferrous oxide (the ore) to leave just iron alone (Fe) as the product.
Pretty sure this doesn't work. Yeah it seems to be high carbon but once you work it, it is basically just mild steel. You can see this on Alec Steele's channel where he used this process to try and turn wrought iron into steel. ua-cam.com/video/3GrRoLhd4H0/v-deo.html is the link.
It has to do with the levels of phosphorous. It inhibits carbon uptake and promotes faster decarburization during forging. This bloomery iron had very low phosphorous as smelted, and gained quite a lot of carbon through this process. If you watch through Alec's video again you'll see them talk about phosphorous being the issue they faced.

Are there going to be follow up videos about the refining of the steel and forging of a tool from it? Would love to see the complete process!
Sorry, no plans for these kinds of follow-up videos at this time. I think other people have already done them, if I am not mistaken.
Great to find most of the answers I was looking for. Thank you
This is great. I'm gonna try this with mild steel scrap I have laying around.
Link for the video with the bloomery?
This is the best explanation AND demonstration ive seen so far! Thank you for sharing this
I sure would like to see you refine that!!!
Great Vid Thank You!!!!
Cool, thanks for sharing.
Can you share where you found the information on the Japanese furnaces? Doing some tool making and want to stay true as possible.

What is the cost of producing 1kg of steel?

stick a bucket or similar, into the loose bricks and it will be way easier to wire it all up.
Interesting
makes me wonder why they didn't just go about trying to produce crucible steel if they were capable of getting temperatures high enough to melt steel.
Those bedammned "inches" again!
Intresting.

Schrodinger555 so how do you avoid the phosphorous problem?
@@shanefoster5305 hearth refining does help drive off excess phosphorus.
You need to start with a low phosphorous content iron ore (haematite).
