Making Viking-Age Bloomery Iron in a Bloomery Furnace

Jeff Pringle and Jim Austin are conducting a Viking-Age Bloomery Iron Smelt in West Oakland, CA. Iron oxide ore is reduced in the furnace to iron. Impurities are removed as molten slag by tapping. The result is a big bloom that can be forged and consolidated using traditional blacksmithing techniques. This is different from making steel from iron ore in that the resulting material is largely free of carbon.
