The enigma of early Norwegian iron production

Ancient Norwegians made top-quality iron. But where did the knowledge to make this iron come from? A professor emeritus from the Norwegian University of Science and Technology may have solved this riddle.

For centuries, people in Norway’s Trøndelag region, in the middle of the country, made large amounts of first-class iron out of bog ore for use in weapons and tools. Production peaked at about 40 tonnes a year at around 200 AD. With production levels this high, it is likely that they exported iron to the European continent as well.

But where did the expertise to smelt the ore come from? And how did it actually get to Norway to begin with?

Arne Wang Espelund, a professor emeritus at the Norwegian University of Science and Technology’s (NTNU) Department of Materials Science and Engineering, has been interested in iron making since the 1970s.

He himself has helped to smelt iron with a method described in the 1700s by Ole Evenstad in Stor-Elvdal, just north of Lillehammer.
