The first man-made iron seems to have been made in Asia Minor around 1500 BC, after a development of furnace technology and established skill for the production of copper and bronze. After field studies in Trøndelag , finds of slag heaps and the use of 14 C-dating, a large and professional production of iron and steel, beginnng about 300 BC and lasting until about AD 500 has been recognized. The raw material was bog iron ore. The paper describes the finds, the extension, the quality of the iron, an interpretation of the process and ends with some thoughts about the organization of the iron age society. Because of the large amounts of an excellent metal an export to the Continent was likely. The technology seems to have been imported from the province Noricum in present-day Austria which was by celtic people (prior to 15 BC).
