Black drawing material made of slowly charred wood and available in varying degrees of hardness, it is one of the oldest materials used for drawing and is manipulated with the thumb or a "stump", a special crayon-shaped implement.

Natural vine charcoal is very soft and can be easily rubbed off with a soft rag. Natural willow charcoal is harder than vine charcoal and gives a darker line. Compressed charcoal is available in several forms. You can choose from stick form, wood-encased pencils, and peel-as-you-go paper wrapped pencils. These charcoal formulations range from extra soft to hard. Powdered charcoal is used to transfer drawings to surfaces by dusting through "pounced" lines on the drawing. ?
