  • How to tell between carbon powder or graphite powder?

    Longer version: First of all, the graphite you were taught about at school is a pedagogical construct. Any macroscopic sample of "real" graphite would contain both the layered honeycomb (crystalline) bits as well as amorphous bits of carbon (in addition to God-knows-what bunch of other substances that managed to wiggle their way into your sample).

    Graphite in its amorphous form is used in the manufacturing of lead used in pencils. Amorphous graphite is preferred as it leaves a dark streak on paper. Finer the powder, darker the smear. In case the graphite is flaky, the smear loses its darkness. It is used in several lubricant products, such as grease and forging lubricants.
