About this video:
While I’m working on other projects I’ll put up this video of an experimental furnace I built that operates by natural draft and uses charcoal as a fuel. The furnace burns the fuel on a grate for maximum area of air entry. The chimney attached to the furnace is 2 m tall above ground level. The pit is 25 cm cubed and extends below ground level. The whole structure took about 2 weeks to build.
A brick of iron oxide (from iron bacteria) mixed with charcoal powder was made and placed in the furnace sitting on a grate about 12.5 cm tall. The furnace was lit with wood and fired. Charcoal was added after this point and a high temperature was reached. The ore brick melted and produced some tiny beads of cast iron.
In contrast to the other furnace I made in the previous video, this one produced less iron while consuming the same amount of charcoal. I’d actually built this furnace before the previous video in an attempt to reduce labour by having a tall draft chimney replace the work and complexity involved with using a blower. I’ll keep experimenting with natural draft furnaces, the principle is sound but the method of introducing the ore (batches of ore on a grate instead of continuous addition of ore pellets) is probably inefficient or could be improved on.
About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials.

I've posted photos of the iron prills that I melted together in a crucible to make a single ingot (it's in my neighborhood tab right here: https://www.youtube.com/channel/UCAL3JXZSzSm8AlZyD3nQdBA/neighborhood?view_as=subscriber) .This modified into as soon as finished the enlighten of the forge blower blasting air down onto the crucible lined with charcoal in a puny furnace. It is indeed iron steel as it sticks strongly to a magnet and has a vivid steel luster. I comprise it to be forged-iron as it is pretty brittle, though in other experiments I've made malleable iron from the identical iron bacteria which shall be flattened when hammered frosty. Thanks.
He's gunna score an i phone pretty soon
most appealing must full this 600 more events before you would possibly presumably presumably score a forged-iron pot and join that douchey neighborhood! yay
Shouldn't you dangle it up when its exquisite red hot? After which u hit it then u save that succor into the furnace? Assuming right here’s a steel oxyde
If the sound of the chiminy falling at the begining modified into as soon as edited i dont are looking to know. It modified into as soon as an unbelievably fulfilling noise.
May per chance well also unbiased gathered you close a purified water arrangement?
