PENCIL POINTS
A "lead" pencil is not made of lead at all, but of graphite with several other ingredients. Pure graphite alone was once used, but it was found to be too expensive, and so a soft gutless clay was added. When the ingredients are mixed in the required fashion, they are squeezed through a strainer, and the long thin rods are placed on a grooved board and then smeared with glue. Another grooved board is clapped on top of it and the two are pressed together. They are then planed off until the pencils are rounded out.
