Here are the basic art materials drawing.
A graphite pencil usually consists of a long, thin cylinder of graphite enclosed in a hexagonal wooden sleeve–the standard pencil. The graphite in a pencil has clay in it to make the graphite more cohesive. The higher the clay content, the harder the lead in the pencil. A very hard pencil lead will make precise marks; a softer lead will leave pigment in a more flowing manner.

Charcoal is slowly charred wood. Large vines are charred in an airtight environment to make bigger sticks of charcoal, while thin willow twigs are charred for other applications when a thin stick is needed. Like graphite, charcoal comes in degrees of hardness. Charcoal is also sold in pencil form.
Conté crayon is a popular drawing material that is similar to chalk but waxier. It is available in sticks of black, white, sepia, bistre, and sanguine. It is difficult to erase.
The soft, slightly sticky surface of this pliable, puttylike eraser allows an artist to precisely lift up a lot of pigment from a drawing without generating “crumbs.”
Draftsmen have worked on virtually every kind of paper produced. Some papers, like Bristol board, are more difficult to erase from. Others, such as newsprint, are not archival. An artist’s choice in drawing paper should reflect the goals of the drawing. Is it meant to be purely a preliminary work in preparation for another piece? Is precision important, and are fine details required? Should the paper be toned in a middle value, or does the artist wish to have the drawing pop off a stark white background?
