Writing Drawing Pigment: Graphite

A pencil is made up of a solid pigment core, usually graphite, encased in a protective wood or plastic casing. The core adheres marks to paper through physical abrasion when drawn across a surface. Pencils create gray or black marks that are easily erased but resistant to other factors, while other pencil cores like charcoal are mainly used for drawing.

A pencil is an implement for writing or drawing, constructed of a narrow,

solid pigment core in a protective casing that prevents the core from being broken or
marking the user's hand.

HB graphite pencils

Coloured pencils (Caran d'Ache)

A typical modern-day pencil.


1. Solid pigment core (typically graphite, commonly called pencil lead).
2. Wood.
3. Painted body.
4. Ferrule.
5. Eraser.

Pencils create marks by physical abrasion, leaving a trail of solid core material that
adheres to a sheet of paper or other surface. They are distinct from pens, which dispense
liquid or gel ink onto the marked surface.
Most pencil cores are made of graphite powder mixed with a clay binder. Graphite
pencils (traditionally known as "lead pencils") produce grey or black marks that are
easily erased, but otherwise resistant to moisture, most chemicals, ultraviolet radiation and
natural aging. Other types of pencil cores, such as those of charcoal, are mainly used for
drawing and sketching. Coloured pencils are sometimes used by teachers or editors to
correct submitted texts, but are typically regarded as art supplies, especially those with
cores made from wax-based binders that tend to smear when erasers are applied to
them. Grease pencils have a softer, oily core that can leave marks on smooth surfaces
such as glass or porcelain.
The most common pencil casing is thin wood, usually hexagonal in section but
sometimes cylindrical or triangular, permanently bonded to the core. Casings may be of
other materials, such as plastic or paper. To use the pencil, the casing must be carved or
peeled off to expose the working end of the core as a sharp point. Mechanical
pencils have more elaborate casings which are not bonded to the core; instead, they
support separate, mobile pigment cores that can be extended or retracted through the
casing's tip as needed. These casings can be reloaded with new cores (usually graphite)
as the previous ones are exhausted.
