Feel the burn

Alright, forget the pretentious retort kiln. The cone kiln is simplicity itself. Just beautiful.

What one can achieve by slight change of degree.

And look at that water coming out at the end of the video. Just as clean as when it went in - cleaner probably.

Also, one can do the same method just by digging a cone pit in the ground.

One thing I did not know was that dousing the hot char with the water expands the porous structure - which is good.

I was wondering after the other video how on earth will I, if I ever really wanted to, do the bio-char that is out of of marmite thing!
Not that I will be burning in a cone right now but it's good to know that I can!
All the char we have is made of wood... is that the same as bio-char?
(Sorry if I sound too ignorant!)

Yes, most bio-char, which is just char added to soil, is made from wood, whether big pieces or small chips. One can also use bone, peach pits, and nut shells!

It's been a while since I had marmite.

It would be cool to do a quiz after burning different things if one can guess what they were before!
Marmite is this big boiling pot he used for the first part of his device in the other video.. or not in English (yes I will consult a dictionary!)?
