Artists' charcoal is a form of dry art medium made of finely ground organic materials that are held together by a gum or wax binder or produced without the use of binders by eliminating the oxygen inside the material during the production process. These charcoals are often used by artists for their versatile properties, such as the rough texture that leaves marks less permanent than other Visual arts media. Charcoal can produce lines that are very light or intensely black, while being easily removable, yet vulnerable to leaving stains on paper. The dry medium can be applied to almost any surface from smooth to very coarse.
