    As pointed out by some viewers on my previous cement videos, this material is probably more of a geopolymer than a calcium based cement, or possibly a mix of the two types, based on the materials that are known to be in wood ash and clay. In any case, it's a material that sets after as little as 6 hours and won't dissolve in water afterwards. All three methods shown here will work, the key being that the ash needs to be heated to about 800c plus with lots of oxygen. This was demonstrated by the uncalcined ash sample dissolving, because it was from an ordinary fire that didn't get hot enough to calcine the ash.

    Three things: First, a reminder to everyone that John puts captions on all his videos to describe his processes. Make sure they're switched-on to understand his vids!
    Second - I've been re-watching the last several videos to try to understand what happened to the ash-insulated furnace from several videos back. You demolished a brick furance to build it, but it seems like the brick furnace is back?
    Third - Is there an advantage to sometimes have a wide-mouthed nozzle in your forge and sometimes a flat-mouthed nozzle? If not, it would seem to me the flat-mouthed nozzle should be default, so you can always have the option to use the clay mold when forging your iron ingots.
    This channel is exceptional and I can't get enough. Thank you!

    • @primitivetechnology9550
      @primitivetechnology9550  6 місяців тому +949

      I demolished it out cause it took up too much room and I'm considering testing different furnaces now. The wide mouthed nozzle is for insitu casting of iron in a mold, the air needs to spread out over the width of the mold hence the shape. The narrow nozzle gives more penetration into the fuel bed which may be better for bloom formation during smelting (not casting). Thanks!

    • @punch1t
      @punch1t 6 місяців тому +84

      For the third point i think i can answer that: The biggest difference between wide-mouthed and flat-mouthed is where you want the oxygen to be concentrated. If you use the wide-mouthed you get a more even distribution of oxygen on the whole fuel while the flat-mouthed focuses on a specific area. if you want even temperature then you go with the wide, if you want high temperature you want to go with the flat. at least thats what i think is happening, if someone knows the science of it they can correct me.

      No it's not. There was a time in the past this was somewhat common, but that is not the case anymore, and hasn't been for a long time.
      In 26/30 MLB ballparks (and a ton of minor league, college, and even municipal fields) the infield is from DuraEdge. Depending on the exact mix used it's ~25-40% clay and silt from a specific area in Pennsylvania blended with 60-75% local sand, this is not fired in any way.
      Some parks and stadiums do use a "calcined topdressing" to add an eighth to a quarter inch of top layer that is made up of fired clay. This can be done for absorbing standing water, or for other purposes. But it's not baked into bricks and broken down, so it's not "crushed brick".

    If i may suggest, heat the wood ash and clay to get something closer to cement. Cement is made of calcium silicates, you got the calcium from the wood ash (Calcium carbonate), silica from clay (Silicon dioxide)(crush it into powder). Mix those two and heat to1450 celsius.
    Tumbling them while heating would help a lot (aka rotary kiln). The Calcium will ditch the carbonate and bind with the Silicon instead creating Ca3SiO5 and Ca2SiO4 and you should be able to unlock the next tech tree.
