A metallurgical examination of a knife made of wrought iron (The experimental smelting in Josefov 2002)
Hošek, Jiří ; Merta, J. ; Malý, K.
The article deals with a metallographical examination of a knife forged out of experimentally smelted iron bloom. The examined specimen has revealed a striped structure with bands enriched by nickel and cobalt. Besides of that a sample taken from the bloom has been analysed. It revealed high carbon content. Due to low nickel content in iron ore as well as in the bloom there is just low probability that nickel-rich bands (less then 2% Ni) of archaeological iron artefacts could be used for an estimation of a nickel content in original ores.
