Metallurgical Provinces of Eurasia in the Early Metal Age: Problems of Interrelation
General chronological frame of the Early Metal Age (EMA) in Eurasia limited from IX/VIII up to turn II/I mill. BCE. The chronological scale of this investigation founded on the systematized date base of more than 3.5 thousand calibrated 14C analyses. EMA can be subdivided into five unequal in chronological sense periods. The Early Metal Age was the epoch clear domination of the western metallurgical centers – particularly up to III mill. BCE. In all probabilities the apogee of the western predominance was incarnated in the immense of the famous Scythian world, in the limits of the first millennium BCE – i.e. beyond the EMA. The eastern centers take up the initiative of westward pressing after collapse of the Scythian world.
Metallurgical Evaluation of Farmer’s Steelmaking in Finland
In this study, we have documented the reconstruction of Finnish traditional steelmaking methods using farmer’s furnace in M?hk? by a local blacksmith, and metallurgically analyzed the materials and products associated with this technology. The steelmaking was successfully recreated in 2007, including mining, furnace construction and operation, followed by forging. Compared with Swedish lake ores, the Finnish lake ore used contains higher iron and lower silicon, aluminum and phosphorus. The produced sponge iron, bloom (luppe), had a yield ratio estimated to be 43–67%. The carbon and oxygen contents near surface areas of luppe were C: 0.32 ± 0.27 mass%, O: 1.20 ± 0.79 mass%, respectively, and those at the centers are C: 0.06 ± 0.06 mass%, O: 0.045 ± 0.030 mass%, respectively. It lacked impurities excluding unexpectedly contaminating ore and slag debris. The reasons for higher yield and lower carbon content were discussed metallurgy. |
