Also called Oil pastel and wax oil crayon, is a painting and drawing medium with characteristics similar to pastels and wax crayons. Oil pastels consist of pigment mixed with a non-drying oil and wax binder. The surface of an oil pastel painting is therefore less powdery, but more difficult to protect with a fixative. Oil pastels provide a harder edge than «soft» or «French» pastels but are more difficult to blend.
Temperature affects the firmness of all oil pastels, student or artist-grade. When warm, they’ll be softer and flow more easily. When cooled, they become more firm.
