A soft, blendable, pigmented drawing stick. Pastel chalks or crayons were first documented by Da Vinci in 1495 with a reference to their use by Jean Perreal in France (Shelley 1999). They became very popular for portraiture in the mid-18th century and were revived in the late 19th century. Pastel crayons are made with a finely ground pigments mixed with a small amount of a water-based binder, such as gum tragacanth or, from the mid-20th century, methyl cellulose. Many pastels contain pure pigments producing intense, deep colors; lighter colors are diluted with an inert filler (chalk, gypsum, talc, kaolin, etc.). Pastels produce a powdery, easily smudged drawing. To minimize smudging, some pastels are 'fixed' or secured with an aerosol-sprayed, thin layer of varnish called a fixative. Fixatives, however, tend change the optical appearance of the pastels.
See also oil pastel.
