Step-10: Final Touches. Graphite, clay, and wood are turned into pencils on an assembly line by mechanical saws, lacquer sprayers, and giant kilns. At sawmills, wood is precut into uniform squares and waxed and stained. Graphite will be held in place by grooves and filled with glue. Clay and graphite are mixed at 1500°C.

Graphitization is a post-process that transforms carbon graphite into graphite. It is often used to improve the material's oxidation resistance and self-lubricating ability. During this process, carbon graphite is heated to approximately 5,000°F in a controlled atmosphere for over a week. Throughout this time, the amorphous carbon matrix ...
