Most historians of metallurgy find it difficult to believe that such control could be developed without some prior experience with high temperature pyrotechnology, such as kiln firing of ceramics or copper smelting.
The earliest-known iron artifacts are nine small beads dated to 3200 BC, which were found in burials at Gerzeh, Lower Egypt. They have been identified as meteoric iron shaped by careful hammering.
