The pine forests, iron was extracted from ore and marsh before 500 AD. The malleable iron was used to produce tools and weapons. Soldiers of the Germanic and Roman armies might have carried weapons forged here in addition to collecting raw iron for later forging where they headed.
In the 15th century, ore was extracted from mines and several ironworks were established. One of these was Hassel Jernverk in Øvre Eiker (1649). Although the king desired canons, the ironworks at Hassel mainly produced cast iron ovens. Skilled workers from Germany, France and Belgium helped build the ironworks. The blacksmiths produced bar iron, anvils etc.
By the beginning of the 16th century, Hassel-ovens were a well known export article from Norway. The ironworks was closed in 1870. Ironworks also found place in smaller farming smiths to produce and repair necessary tools. These no longer exist.
