Main parameters of our model in comparison with other estimates of the resource consumption of early iron smelting.

Studies are ordered from low to high. Furnace efficiency in brackets is without preheating and reheating. Notes mark the data source of the respective studies. For studies where a range of values is given, medians were estimated.所有研究均按从低到高的顺序排列。括号内标注的炉体效率未考虑预热与再加热过程。备注标注了各项对应研究的数据源。对于给出数值范围的研究，已估算其中位数。
