Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earth's softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils. Even modern pencil 'lead' is composed of graphite mixed with clay. Paradoxically, even though graphite is ...

The pencil manufacturing process has indeed come a long way. Today, most wooden pencils are mass produced from large blocks of cedar cut into slats. A machine cuts eight grooves, half as deep as the graphite-clay rod is thick, into the slats, and then places rods in each groove. Once the rods are in place, a second grooved slat is glued on top ...
