  1. Stefan Roth destructive testing on japanese and european swords (in german). (You can turn on subtitles with "CC" button) Skip to 21 minute mark for the test. I find it a fun combination of exhilaration and cringe to see this. Any thoughs on the implications? Was it a "fair" test?
  2. Very creative and sexy stuff here! I've seen nothing like it before. The satisfaction and joy that crafting brings shines through the pictures in this project.
  3. I don't know about your Tatara. Maybie you do melt it. Do you load it with charcoal from wood? Edit: Looking at your thread "Pit Charcoal" it does appear to be partially melted. Very nice post! Found this post by Niko. Here its typical smelted appearance. No iron here has become fully liquid. Traditionally its smelted, not melted. Ore gets reduced by CO(g), the rest melts away as slag. Iron gets carburized. Trick is to have a reducing flame by using a oxygen deficiency. In this case we don't need experimental archaeology. We can turn to the modern Japanese as some people th
  4. Japanese tamahagane/shingane was (and is) really high quality bloomey steel. The ferrous material is never melted. The tatara furnaces used for smelting japanese bloomery did not produce high enough temperatures to melt iron. It's acually really similar to what we did in Europe before the industrial revolution. Crucible and wootz has been explained here before. The big difference is that the ferrous material is completely melted due to the higher temperature of that type of furnace. Because of this the iron needed to be sealed in an airtight container, a crucible. Edit: Maybie
  5. The Ulfberts are a cool mystery. The name is Franskish. The letters are roman not viking, and the cross is Christian. Yet most blades are found in pagan Scandinavia. most people seem to think the name refers to a Bishop. Bishops of these early christian germanic types were more like warlords. They did not do this "turn the other cheek" thing. Jesus was still a little bit like Tor. If they were made from Asian/Indian crucible steel, the Vikings could have traded for it in Persia (or maybe Constantinople/MiklagÄrd?) via the Volga river trade routes that leads to the Black sea or the Caspian
  6. Maybe, maybe not. There is however quite a lot of evidence. Although evidence does not equal proof. It's almost impossible to scientifically determine the ore source of a historic steel. I think isotope analysis might yield some answers? -The first evidence is that it's possible to make from this ore and it contains vanadium. Vanadium carbides are like you said not necessary but they are very well suited to seed the formation of cemetite bands because the vanadium carbides are very hard to dissolve. -The second evidence is that there is a castle guarding the mine. Saladin used it to
  7. Yes I also think a lack of ore played a role. Compare it to the American gold rush. You can still find gold from California to Alaska, but it's harder and harder to get. At some point the amount of time and resources that needs to be spent will outweigh the gains.
  8. I love stuff like this! Like Wes I'm very interested in the gun barrel steel, did you spark test it? Also since I got you pinned down here on the forum I like to thank you so much for all your Youtube content. I basically learned bladesmithing from watching your stuff.
  9. Welcome! I think the most interesting part of the documentary is that it shows us a new location for wootz production. The mine in question was in use by Saladin among others, and he built a caste to protect it, showing its significance. The ore contains vanadium "in the sweet spot" of around 0.08%. These two facts I think proves that not all wootz came from India or central asia but also the arab levant. Exiting stuff!
  10. Hello fellows. This documentary is made by Mike Loades. It follows the work of the late Al Pendray (rest in peace), Dr John Verhoeven and two bladesmiths from Jordan. They recreate faithfully wootz using ancient ore from a mine in Jordan, south of Damascus. This particular mine has a historic significance. They make bloomery from the ancient ore and then create crucible steel from old recipie with no modern additions. Just the unrefined bloomery, charcoal, fresh green leaves and crushed glas as flux. As far as I know this is they most authentic recreation of ancient wootz, using
  11. It's still not heat treated! I might be able to do it before before the end of the year, but I don't have a solid location yet. I'm a little worried the edge is on the thin side for the quench but I have to try it anyways. I want a hard edge! I'll update once the project has moved forward with new photos. Might take some time but I will finish the wootz sword!
  12. This is an epic project! Is that whole beauty made of melted down nails? Early iron age is so mysterious and your project is incredibly exciting to follow. Thanks for sharing.
  13. Very nice work! It looks slender with nice lines and the wood structure matches the steel pattern. Handle resembles katana bevels, never seen that before.
  14. I've seen you on youtube, nice to see you here as well and this very nice and clean tanto.
