I decided to scan a small piece of frit (glass shard).  The SEM machine was malfunctioning (joystick not working to move around the piece) while it was my turn, but I still got a few interesting images out of the process.  I feel like I learned more about what a SEM machine is and also just how cool things look when you zoom in close.  Even the most mundane objects look fascinating.  I really enjoyed looking at the stress marks where the glass was broken.  It gives almost a history of the piece of glass when you get that close, as the stress marks can give information to speculate on how the piece was broken and by what.
