Similarly,iron smelting during the antiquity was also extraordinarily inefficient and medieval practices brought only marginal improvements.Johannsen (1953) estimated that medieval bloomery hearths required at least 3.6 times,and as much as 8.8 times,weight of fuel than the mass of ore.Cast iron metallurgy BritannicaCast iron,an alloy of iron that contains 2 to 4 percent carbon,along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus.It is made by reducing iron ore in a blast furnace.The liquid iron is cast,or poured and hardened,into crude ingots calledCast iron metallurgy BritannicaCast iron,an alloy of iron that contains 2 to 4 percent carbon,along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus.It is made by reducing iron ore in a blast furnace.The liquid iron is cast,or poured and hardened,into crude ingots called
