Excerpts from ART HARDWARE: The Definitive Guide to Artists’ Materials, by Steven Saitzyk © 1987 Dry drawing materials are either carbon-based or chalk-based. Although the use of both types dates back to prehistoric times, carbon-based drawing material, and particularly charcoal, is credited with being older because it was common to every fireplace, whereas deposits of pure chalk are quite rare. A dry drawing material can be easily applied to any surface as long as the surface has some tooth to bite and hold its powdery consistency. It can also be easily blended or erased. Blending can be done by rubbing or by wetting the drawing with either water or turpentine. At one time, a technique was developed of dipping the dry drawing material first in a drying oil, such as linseed oil, to create a darker line and improve adhesion. However, this tends to form a yellow stain around the edges of the applied drawing material and to acidify and rot the paper. The primary disadvantage of dry drawing materials is the difficulty of storing and protecting the final drawing. The use of a fixative will help, but it will not completely protect the surface. Protective coatings and picture framing in combination provide the only long-term protection. Carbon-Based Drawing MaterialsChalk-Based Drawing Materials
