3DCast ingot.
This is a lovely little cast ingot with a broken side that lets you see a different kind of surface. It weighs about 40 grams. Unfortunately, due to a screw up in sample counting, I had to put this sample into the beautiful periodic table display that now graces the Julian Science Center at DePauw University. It's the prototype for a line of museum displays that Max Whitby and I are now building, and being the prototype we made a lot of, um, learning experiences in its construction. One was that the germanium sample that was supposed to go it it was in England at the time, forcing me to take up the slack with this one. Not to worry, Max is sending me more germanium: He buys it direct from China now.
