Colored pencils (US English). ]] A crayon is a stick of colored wax, charcoal, chalk, or other material. A crayon made of oiled chalk is called an oil pastel; when made of pigment with a dry binder, it is simply a pastel. A grease pencil or china marker (UK chinagraph pencil) is made of colored hardened grease. Some fine arts companies such as Swiss Caran d’Ache manufacture water-soluble crayons.
