Thanks

There's actually a bit more to the chemistry of smelting than he mentions. It's not only the higher temperatures that are important, carbon monoxide is used to extract the base metal from the ore (which is usually an oxide).

If he's been relying on ancient sources, they may well have not mentioned the chemistry since oxidation and reduction were only really properly described in the 18th century (oxygen was discovered in 1772) and not all historians have a good grounding in chemistry.

This is a great video and one of my favorite things about it is that his video description answers the very question I had immediately after watching it. I had never really wondered why people use charcoal instead of just the wood it's made from.
