Wow, I guess it has been a while since I have added to this blog. Recently, I found several unused flashbulbs produced by General Electric. Each bulb contains very fine wire which resistively heats and burns in the oxygen atmosphere of the bulb, producing a bright flash. Felicia Staiger acquired a scanning electron microscope image and an energy-dispersive X-ray spectrum of the wires. The spectrum indicated that the wires were comprised of aluminum.
