Dry Media: Crayon  

The increasingly undependable supply and inconsistent quality of natural chalks created a demand for artificial products that would be more easily obtainable and used. When the pigments are combined with oily, greasy, or waxy binding media, a crayon is produced. This makes a line which is both richer in texture and more permanent than natural chalks, and artists had to adjust their technique accordingly. A particular formula was devised by Alois Senefelder, the inventor of lithography, for use in his printing process. He designed it specifically for drawing on the printing stone, but artists also used these crayons to draw on paper.
