• Smelting

    Being smallscale batch operation—every heat was terminated in order to remove relatively small masses of the solid bloom—iron smelting in traditional lowrise bloomeries could never supply largescale demand for the metal in an economic way, and laborintensive (and also highly energyintensive) forging added to the cost (further increased by substantial losses of iron during the forging ...
