OILPASTEL
Oil pastel
Oil pastel is a painting and drawing medium with characteristics similar to pastels and wax crayons. Unlike "soft" or "French" pastel sticks, which are made with a gum or methyl cellulose binder, 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.The above text is a snippet from Wikipedia: Oil pastel
