The amazing man who produces iron using only wood, bark, fibre and clay

The popular Primitive Technology blog features an unnamed man in Far North Queensland, Australia building tools and structures using only raw, found materials. In this instalment, the man builds a new device he refers to as a ‘bow blower’ – a combination of a primitive drill and a manually powered fan – used to keep a fire burning hot enough to produce iron. The result is a stunning combination of ingenuity, expertise and determination. To learn more about the step-by-step process while watching, turn on closed captions in the YouTube video player.
