Match Heads

This Nano Gigapan shows two match heads side by side, illustrating the difference (as seen under a scanning electron microscope) between a unlit strike anywhere match and one that has been burned. This difference is clear with the naked eye, but can you tell which has been burned looking at it with a different tool? This image is composed of 140 pictures of matches magnified 150x.
