What is a Pencil Made Out Of?
A pencil is primarily made out of wood and graphite. The graphite is ground down and mixed with powdered clay and water to make a thick paste. This paste is then fired in a kiln. The result is a strong lead core that's difficult to break and extremely smooth for writing on paper.
Rubber and aluminum are also part of a pencil's anatomy. The rubber is used to make the erasers, while the aluminum creates the ferrules that hold the erasers in place. You wouldn't be able to fix your writing mistakes if it weren't for these two pieces!
