Macrophotograph of a specimen of pure 99.999999 Silicon. This is the poly-crystal Silicon that is left at the bottom of the crucible after the single crystal is grown and removed. The pure Silicon crystal is cut with diamond saws into thin slices called wafers and the chips are photo etched onto the surface. The remaining poly crystal Silicon is now used primarily to make solar cells. There is enough Silicon in this piece to make many hundreds of computers. Object size: approximately 36x42 mm.
