Making Biochar with a Simple Kiln

The first 2 times I made coal was with a open burn pile of cutoffs from my sawmill. I built the pile to collapse and smother itself while burning. It generated a good amount of coal but required much more water, was time consuming, labor intensive, unpleasant, and somewhat dangerous www.treebased.com/blog/making-biochar. It required much more tending and interacting with the fire than cooking in a simple kiln.

It's probably much easier to make charcoal out of even length/width flat slabs but it happens to be the way I make it so I thought I'd share. Enjoy!
