How to make charcoal with nothing but wood, leaves and mud.
Day 11 in Tollan. The storm is over. The house stayed dry, but the old leaf hut caved in. The river cut deeper into the bank, and below the clay there's a band of heavy, rust-red stones. That red is rust: there's iron inside.
You throw one in the fire and wait all afternoon. Nothing happens. It's just a hot rock. A wood fire isn't hot enough to get iron out of rock.
So Mati shows you how to make charcoal. Stand the old hut's poles up tight on bare dirt, well away from the house, with the thickest ones in the middle. Cover them with leaves, then pack on mud a hand thick. Leave one hole at the top and poke small air holes around the bottom. Drop hot coals in the top hole and watch the smoke: white means the water is still cooking out. When the smoke turns thin and blue, then clear, seal everything and leave it for two days. And never burn charcoal inside.
The wood was wet, so the smoke went on for hours. And you can see it for miles...
