In 2013, a single bead from the Manchester Museum (UK) was photographed, subjected to a scanning electron microscope to reveal the bead's micro-structure and chemistry, and an X-ray CT model (or scan) of the bead was produced. The results indicated the beads' micro-structures and composition were consistent with that of an iron meteorite that had been worked into a small thin sheet and bent into a tube-shaped bead. Hence, "for the first time using modern technology [researchers] recorded conclusive proof that the earliest known use of iron by Egyptians was from a meteorite."[1]
