Found in the middle of rotten logs, punk wood is in the process of rotting but hasn’t turned soft. It can be obtained by knocking or kicking apart rotten logs. It can be broken with the fingers but doesn’t crumble. Punk wood is very light in weight, but still fairly firm. If dried out, it will light very easily since it is already well mixed with air. If charred like char cloth, it will catch and burn from a spark. The process for charring punk wood is the same.
