Acheson in the mid-1880s. Acheson, a former assistant manager for Thomas Edison, conducted experiments in his laboratory in Pennsylvania. He aimed to create man-made diamonds by dissolving carbon into molten corundum using intense heat from electrical furnaces. While diamonds weren't produced, he discovered a substance second only to diamonds in hardness and abrasiveness. Originall
