A
Crayons and pastels are made of powdered pigments, the same as those used to make paints, mixed with a binder. For crayons, the binder is a greasy or waxy substance. Finer, denser, more brilliant versions of these crayons have been developed for artists. Pastel consists of pigment bound with a nongreasy binder.
