reports on an article behind a paywall: Analysis of a prehistoric Egyptian iron bead with implications for the use and perception of meteorite iron in ancient Egypt Diane Johnson, Joyce Tyldesley, Tristan Lowe, Philip J. Withers, Monica M. Grady. Meteoritics & Planetary Science online: 20 May 2013 DOI: 10.1111/maps.12120 http://onlinelibrary.wiley.com/doi/10.1111/maps.12120/abstract Abstract: Tube-shaped beads excavated from grave pits at the prehistoric Gerzeh cemetery, approximately 3300 BCE, represent the earliest known use of iron in Egypt. Using a combination of scanning electron microscopy and micro X-ray microcomputer tomography, we show that microstructural and chemical analysis of a Gerzeh iron bead is consistent with a cold-worked iron meteorite. Thin fragments of parallel bands of taenite within a meteoritic Widmanstätten pattern are present, with structural distortion caused by cold-working. The metal fragments retain their original chemistry of approximately 30 wt% nickel. The bulk of the bead is highly oxidized, with only approximately 2.4% of the total bead volume remaining as metal. Our results show that the first known example of the use of iron in Egypt was produced from a meteorite, its celestial origin having implications for both the perception of meteorite iron by ancient Egyptians and the development of metallurgical knowledge in the Nile Valley. The Nature write-up includes a quote from a museum creator that "during the time of the Pharaohs, the gods were believed to have bones made of iron". - Robin ______________________________________________ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
