Then we added a 40x microscope lens to try for better magnification; each tick mark is 10 microns, or 0.01mm:
Above is a nice sharp-edged piece, at ~50 microns or so.
Above, some interesting grooves and darker colors in there. This is in beet juice to add contrast but maybe that was unnecessary.
Finally, there were a lot of these smaller very sharp shards, at ~20x5 microns, perhaps:
And from last week's #microbrews event:
