| | |   Oliver Sacks' slab.  (External Sample) This iridium was original sold to Sacks by my friend Max Whitby in the form of marble-sized buttons.  Sacks wanted it in the form of a single large slab, and in the summer of 2004 I got a chance to visit Kaistar R&D in New Jersey with him.  Kaistar is run by a family of Russians and they have the lovely electron-beam furnace you see here, with Sacks in front of it holding his newly minted  1.7 pound lump of solid high-purity iridium.  Read my story about the trip for more information and pictures of what goes on inside the furnace.
