pastel

pastel (păstĕl`), artists' medium of chalk and pigment, tempered with weak gum water and usually molded in the form of sticks; also a work done in this medium. Pastel was in use in Italy in the 15th cent. and is doubtless much older. It was introduced into 18th-century France by the Venetian artist Rosalba Carriera. The medium was then used by such masters as Maurice Quentin de La Tour and Vigée-Lebrun, and in the 19th cent. by Degas, Manet, Toulouse-Lautrec, Whistler, and Cassatt. In the 20th cent. Matisse was a master of pastel. Pastels are often classified as paintings, although the medium lends itself to the more direct and spontaneous approach of drawing.

pastel

Drawing medium consisting of fragile, finger-size crayons called pastels, made of powdered pigments combined with a minimum of nongreasy binder (usually gum tragacanth or, from the mid-20th century, methyl cellulose). Because pigment applied with pastel does not change in colour value, the final effect can be seen immediately. Pastel remains on the surface of the paper and thus can be easily obliterated unless protected by glass or a fixative spray of glue size or gum solution. When pastel is applied in short strokes or linearly, it is usually classed as drawing; when it is rubbed, smeared, and blended to achieve painterly effects, it is often regarded as a painting medium.
