Silicon Four and a half pound lump
Four and a half pound lump.
This is a really great rock of silicon. I don't know the purity, but this is probably one of the intermediate stages in the purification of silicon from sand to boule, so I'm guessing it's around 5-nines, but this is just a guess. What I do know for sure is that it's a wonderful thing to hold, with the typical shiny metallic-yet-not-metal surface of silicon. The next stage in purification is the rod pictured above, and the step before this one is the lump pictured below.
