Meanwhile,
Richard, holding sand, entered Eden.
He walked into the main laboratory and poured the sand into a funnel-shaped container, starting the process of washing, sieving, and filtering. After several steps, he obtained qualified pure sand.
He transferred the purified sand to another cylindrical container, mixed in a large amount of coke, and placed it into a special melting furnace for heating.
During the heating process, the sand made noises, which Richard knew was due to the reaction of Silicon Dioxide (SiO2) in the sand with the Carbon (C) in the coke, eventually producing metallurgically grade coarse silicon (Si) with a roughness of about 98%.
