04The process they use is called pyrolysis. It involves vaporizing all the other compounds in the wood, leaving only pure carbon. To turn these massive piles of timber into charcoal, they first stack the wood in one of 28 purpose-built kilns. But if you just set fire to this lot, you'd end up with a pile of ash, not charcoal. If we didn't control the airflow we would end up with ash. To stop the log pile from becoming a towering inferno, they restrict the flow of oxygen with a series of air vents. There are holes at the base to bring in clean air which is essential for the burning of charcoal.
