1)You use a few kilo's of stone and some hard labour to make a coke oven.
2)You then go and gather coal and wood
3)You then use the coal and wood in the oven to make char-coal. Which diminishes in weight obviously
4)Now this is the real bane, when you use coal/charcoal to refine iron ore, it takes more charcoal than it would coal to make the same amount of iron, so why the hell would anyone use there more efficient coal to make less efficient charcoal at the same time burn a load of precious wood in the the process!!
Does this make sense !
It doesn't make sense to me
