raudanvalmistus II by jarkko1 raudanvalmistus II by jarkko1
Toinen yritys valmistaa rautaa muinaisin konstein. Kuva valmiista puukosta, jossa juuri tuo kuvasarjassa syntyvä terä, löytyy täältä jarkko1.deviantart.com/art/mal… kuvasarja syksyn 2012 kokeilusta löytyy täältä jarkko1.deviantart.com/art/rau… ja senkertaisen valmiin puukon kuva täältä jarkko1.deviantart.com/art/mal…

Another attempt to make iron in ancient way. Finished knife with that blade can be seen here jarkko1.deviantart.com/art/mal… photos about previous iron making time can be seen here jarkko1.deviantart.com/art/rau… and finished knife of that time is here jarkko1.deviantart.com/art/mal…

1. Rautamalmin etsintää ja keräämistä joen pohjasta.

Searching and collecting the bog iron ore from the bottom of the river.

2. Joen pohjasta nostettua järvimalmia.

Bog iron ore from the river

3. Malmin puhdistamista polttamalla, eli pasuttaminen

Cleaning the iron ore by burning it.

4. Pasutettua malmia, seassa myös hiiltä ja tuhkaa polton jäljiltä.

Burned iron ore, also some charcoal and ash there.

5. Puuhiiltä pelkistyspolttoa, "sulatusta", varten. Hiilen ja malmin lisäksi lisäsin masuuniin hieman kalkkia, jonka pitäisi auttaa kuonaa sulamaan helpommin.

Charcoal for the smelting. Besides ore and charcoal, I also add some lime into furnace, it's supposed to help the slag smelt better.

6. Malmin ja hiilen lisäystä masuuniin sulatuksen aikana. Masuuni on koottu kivistä ja savesta.

Smelting ongoing and adding some ore and charcoal into furnace. Furnace is made from stoneblocks and clay.

7. Näkymä masuuniin.

View to the furnace.

8. Sulatuksessa aikaansaatu möhkäle, joka sisältää pääasiassa kuonaa, mutta myös rautaa.

After the smelting there is lump that contains slag and iron.

9. Rautaa sisältävät palaset kuonakasasta eroteltuina. Nämä rautapalat sisältävät silti yhä runsaasti kuonaa.

Pieces containing iron, separated from slag lump. Although these pieces still contain lots of slag in them.

10. Rautapalaset ahjohitsataan yhteen ja niitä aletaan takoa kiinteämmäksi. Kuvassa ahjohitsausta konevasaralla, sula kuona-aines lentää pois raudasta komeina kipinöinä.

Iron pieces are forge welded together, and they are forged more solid. In photo there is forge welding with air hammer. Melted slag flies off as sparking.

11. Rautapalat kahdeksi möykyksi ahjohitsattuina. Nämä möykyt ahjohitsataan vielä yhteen.

Iron fragments forge welded into two pieces. These pieces stil need to be forge welded together.

12. Rautapala venytetään takoen, taltataan keskeltä ja käännetään kaksinkerroin, tai useamminkin, päällekkäin. Tämän jälkeen se ahjohitsataan jälleen yhteen ja samaa vaihetta toistetaan kunnes raudasta on tullut kyllin kiinteää ja tasalaatuista käytettäväksi.

Iron is forged into flat piece, cutted from the middle, folded and forge welded solid again. This is then repeated many times, as it makes the iron piece more homogeneous and solid.

13. Kun rautapalasta on saatu taottua kyllin tasalaatuinen, voi sen muotoilla esineeksi. Tässätapauksessa puukonteräksi. Ja lopuksi vielä valmiiksi työstetty puukonterä. Satunnaisesti hiiltä sisältävä malmirauta ei tietenkään ole mikään ihanteellinen puukonterämateriaali sellaisenaan, mutta varmaan historianhämärissä on tällaisiinkin teriin jouduttu turvautumaan. Yhtä aiemmin valmistamaani "malmiterää" olen testaillut, ja ainakin kevyttä käyttöä se tuntuu kestävän kohtalaisesti, mitään kovapuita taikka oksapalikoita on tietenkin aivan turha mennä tällaisella terällä vuoleksimaan.

When iron piece is solid enough, it can be forged into new shape, this time I forged a knife blade from it. And finally in the last photo, there is finished blade. As this kind of iron contains carbon coincidentally, its not too good blade material as such. One blade that I made same way earlier can be used pretty well in light jobs, but it does not stand heavy use, such as carving hard or branchy woods.




And like at previous time, some of those pictures are taken by :iconaneesan: And she also assisted me in this project.

Edit 27.2.2014

Toisesta aiemmalla raudanvalmistuskerralla, samalla tekniikalla, tekemästäni terästä tehtiin analyysi. Terän hiilipitoisuus oli noin 0,531%. Näytteet otettiin kahdesta kohtaa terän keskeltä.

Analysis was made for another blade, which I made when I first time made iron, with similar method. Its carbon content is about 0,531%

When you collect the bog iron ore from the river, how do you recognize it as such? How do you know it's not just a regular stone? Do you just pick up hundreds of stones and examine each one, or do you know even when it's still at the bottom?

The iron ore is really different than stones actually. It's bit like hard sand lumps sticked together and it can be crushed by hand. I tap the bottom with oar and it can be feel when there is ore instead of mud or stones.

Awesome work! I sadly only tried smelting with rust and old nails, but the outcome was pretty simmilar. (Plus second degree burns on my legs, as we had a bit larger bloomery and I for Gods know why decided to take shorts when working with a lot of fire :D) Have you tried smelting/recycling just regular rusty iron? If so, could you compare it to smelting with ore? I imagine that added stepps of baking and crushing the ore are the biggest difference, and maybe more slag? Anyway, thank you for posting this here, now, when I describe someone how steel was made back in the olden days, I can show them this. :-)

I have not smelted rusty iron, but I would imagine that it makes somehow same thing, but with less slag. Smelting separates iron from ore, and most of the ore is just slag, but with already clean iron the iron pieces should just stick together making cleaner lump.

how do you know if the spot contains a good ore of bog iron?

Well, the ore is pretty easy to find by trying the bottom with oar, as it feels different than sand, stones or mud. Iron ore is pretty common in waters of eastern finland. I didn't weigh the ore that I used for smelting, but there was pretty much of it.

This is amazing; I have a lot of admiration for these methods.

Have you seen this doco Secrets of the Viking Sword [link]?? It's really interesting, and contains some ancient methods for purifying steel, and making a mark.

I have seen that documentary. Interesting subject ofcourse, and blacksmith there was skillful also. But entirety was bit poor, I think. By the way, many of those ulfberhts have been found from finland.

You can try bottom of the water with oar, for example. If it feels that there is ore, then just dig it up. Its pretty common in waters of eastern finland.
