Dry media paintings or drawings are representations of forms, objects, or ideas on a surface, drawn by hand with dry pigments, usually compacted in forms of sticks or pencils, like pastel, graphite, charcoal, etc. 

My favorite dry media are pastel, charcoal, and woodless pencils, graphite HB to 9B, or pigmented.

Graphite is the most stable form of carbon, and a form of coal.

Charcoal is the lightweight black carbon and ash residue hydrocarbon.

Pastel is an art medium in the form of a stick, consisting of pure powdered pigment and a binder. The pigments used in pastels are the same as those used to produce all colored art media, including oil paints. The binder is of a neutral hue.
