Looks like Carborundum.
Carborundum is actually the worlds very first artificially produced mineral. In the mid 1880’s an inventor/scientist
named Edward G. Acheson, who had worked as assistant manager of European interests for Thomas Edison,
started his own experimental laboratory in Monongahela City, Pennsylvania. He had a crazy notion that he could
produce man made diamonds by dissolving carbon into molten corundum (natural aluminum oxide) with intense
heat from electrical furnaces. His experiments failed to produce diamonds of course, but he actually produced a
substance that proved to be second only to diamonds in hardness and abrasive ability. Since this product came
from a compound of Carbon and Corundum, he named it “Carborundum”. Years later a chemical analysis
determined the substance to actually be silicon carbide.
