Pencil

Just need a human.

  • A pencil is a utensil that is used for writing or drawing  and includes many types like graphite, charcoal, carbon, coloured, grease and watercolour pencils.
  • Early pencils were a stylus made from a metal rod or lead.
  • In the 1500s, a great marking substance was discovered, and at the time it was thought to be a type of lead, hence the name ‘lead pencil’.   It was graphite, and most pencils have contained graphite ever since.
  • Pencils typically have a cylindrical wooden casing which helps prevent the core (or lead as it is known), generally a mixture of graphite and clay, from breaking and prevents colour transferring to hands.
  • The word ‘pencil’ comes from the Old French ‘pincel’ meaning small paintbrush.

  • The largest pencil was finished in September, 2007 and measured 23 meters (76 feet) in length and 8,200 kg  (18,000 pounds) in weight.
  • Pencils come in a variety of shapes and designs, including hexagonal, cylindrical or rectangular shapes, as well as mechanical pencils with a plastic casing and propelling leads, and flexible pencils.
  • Pencils have a hardness (H) and blackness or softness (B) rating system. Adding a number in front of a H or behind a B indicates the rating of hardness or softness.
