Bog iron - Wikipedia

First iron smelting attempts date back to the 2nd millennium BCE in the Near East. The technology then spread throughout Europe in the following two millennia, reaching Poland in the 2nd century BCE. Iron production reached Scandinavia around 800-500 BCE. Iron production sites in central Sweden are dated to the late Bronze Age and the innovation might have been transmitted from both the south and the east. The ore used was limonite in the form of red soil and bog ore. Fro
