This is fascinating, Kelpie! I started translating some of the captions from Polish on Google Translate... they have a sealing clay layer over the top, and materials like coniferous wood and birch bark around the sides of the pile (for kindling, I guess?)

Would the vinegars still form and drip down if the fire were not capped off like this?

Hi Brian,
I would guess that the clay is to hold the heat in so it can cook a long time. Probably they are trying to minimize the amount of fuel used, so clay would help conserve heat. But if you are just piling on more wood to make biochar, I bet you don't need the clay. Thanks for translating!
