An informational film about the production of silicon carbide, a synthetic mineral.
An informational film about the production of silicon carbide, a synthetic mineral. After the first few images are shown of a sand grindstone from the era before silicon carbide (depicting an old man with a long white beard working with a sand grindstone), we see the different stages of how silicon carbide is produced, with explanations offered in the intertitles. Coke, sand, sawdust and salt are fed into electric furnaces that burn at six thousand degrees Celsius. Factory labourers work the large chunks of the material, which are crushed into pellets from crystal masses, while female workers cast small wheels of the material; one woman is shown in close-up. The film ends with the old man from the beginning, who is now working with a grindstone made of silicon carbide. This is followed (in the Dutch copy) by a short cartoon of Emperor Wilhelm II, whose nose is placed against a grindstone, resulting in a piece of paper entitled “Willie's record” (his death list) being splattered with blood.
