  1. The patina turned out beautifully.
  2. Very natural pose for the cat and it fits just right with the background. Using images that are close to you as inspiration certainly works for you. Can't wait to see it after the patina, Tiaan.
  3. Geoff, there is no need to start a new thread. Go over to the bloomers and buttons section and search for Aristotle furnace or Ole Evenstad. The process of carburizing iron in an open charcoal fire has been described there.
  4. I would be careful about about making an absolute statement like " You cannot carburize iron in any kind of open system. " I will be glad to show you how I can carburize in an OPEN charcoal fire or even in my propane forge.
  5. I have also tried this technique and successfully welded mild steel and wrought iron with it, drew out the billet and COLD worked the edges after turning it 90 degrees causing severe deformation (upsetting) looking for delaminations but saw none.
  6. Good job, Jan. Use a bar as thick as the billet. It will last longer.
  7. I was not very clear in my description. One of the most common methods of patina in Japan is called niage. For this patina you mix rokusho and cupric sulfate in varied proportions and concentrations. As Tyler said, I suggested a simple method of approximating the rokusho component of the niage patina. What I described is called vergigris in Western terminology. The composition of verdigris is variable and could be copper acetate (if vinegar is present) which is mainly green in color or copper chloride (when sea salt is in the mix) or copper carbonate and other copper salts in various composit
  8. Vinegar and salt left alone in a copper pot for a good while could be used in a pinch as an alternative to the commercial rokusho.
  9. Masterful. No need to comment on the details, simply sit back, contemplate and take it all in. There is a lot to notice.
  10. Great job, Jack. I particularly like how you oriented the grain of the steel.
  11. I like the pattern on the first one. Very organic.
  12. Jan, have you been able to forge/weld any of your decarburized cast iron?
  13. Yes on the cross bar (hadome) for me. I would also add the end cap (ishizuki) and some other adornments (bands). Looking good.
  14. Way to go, guys! Thank you to EVERYONE who attended, participated or helped in the event. Specially to our gracious hosts for doing it again a seventh time. I came back home with 13-14 kg of cast iron from the smelt which will be put through experiments aimed at decarburizing and making steel hopefully worthy of turning into blades. I greatly enjoyed the company of all. Thank you.
  15. You are bad, Doug. You can't do that to me. Now the wait it's going to be even worse!
  16. Looking forward to the event this year. I plan on running a full smelt with the help of Denis. Mark, Zeb and Chris will be busy burning holes in everyone's shirts running hearth furnaces. We can always use help Friday getting the charcoal chopped and ready to burn on Saturday. Denis and I will arrive around noon on Friday to set up the smelter. I have a plate and a fork already in hand for the moment Doug says go!
  17. Nah. The wagon with all the food. BTW, I just recalled that we did all this without a scale to weight the ore but fortunately we had Denis' fancy charging tools.
  18. I was not worried, that's just the way I look when I am thinking. I feel that we worked together very well as a team, each one of us making the best of our own skills and contributing to a good end.
  19. Thank you, guys for a great time. Regardless of my opinion about the nasty slag and how it keeps destroying my furnaces, the iron bloom we made was one of the most dense and solid that I have ever seen.
