In a slag-pit furnace process only barren rock was melted which together with not fully reduced ferrous oxides created liquid slag. It was calculated that in order to obtain a block of slags weighing about 100kg about 200kg of ore needed to be melted and 250-300kg of charcoal to be burned. The whole process would have to last almost 24 hrs.
