How do you make a pencil?
At the factory where pencils are made, a long, thin groove about 1 mm long is made in the vertical direction on a long, thin board, and a lead is placed inside the groove. Before going into the process of making pencils, let us explain the inner core.
The core of a pencil is made of graphite. Graphite is written as "black lead," but it is actually a member of the charcoal family, not lead.
This graphite is pure black and can be easily crushed into a fine powder. When powdered graphite is mixed with clay and baked, the pencil lead is produced.
This graphite pencil lead is placed in the groove of the board as explained in the previous section. Another similar board is placed on top of the board on which the pencil lead is placed, and the top and bottom boards are glued together. The glued boards are immediately scraped into the shape of a hexagonal pencil, and then cut into pencil lengths one by one.
For your home
As the pencil is written "pencil (namari no fude)" in Chinese characters, people used to write letters and draw pictures with namari or silver.
