I did not think to adequately shake the box of 550 particles before skimming some of the grains off the top surface for SEM. So most of the fine fragments are likely at the bottom of the box. (The box did get turned upside-down a couple of times, but I doubt it was enough to re-distribute the particles sufficiently.)
