The ingot
All the world's electronic silicon is pulled from a molten bath, crystal by crystal.
Almost all the world's electronic silicon is pulled from a molten bath, crystal by crystal, from a seed no thicker than a pencil. In a quartz crucible, polysilicon is melted at 1,414 °C. A seed crystal is dipped into the bath, rotated, and raised very slowly: silicon freezes onto it, copying the seed's perfect order. In a day or two, the ingot grows into a cylinder taller than a man, a single flawless crystal. The process bears the name of the Polish chemist who discovered it by accident, dipping his pen into molten tin instead of the inkwell. Pull the ingot: that is the gesture, at the scale of a factory.
