Pencil Drawing

These are the most common types of pencils, and are encased in wood. They are made of a mixture of clay and graphite and their darkness varies from light grey to black. Their composition allows for the smoothest strokes.
• Solid Graphite pencils
As the name implies, these are solid sticks of graphite, about the diameter of a common pencil, which have no casing. They are used primarily for art purposes as the lack of casing allows for more interesting effects. They are available in the same darkness range as wood-encased graphite pencils.
