Oil pastels are a type of art medium made from pigment mixed with a non-drying oil and wax binder. They are known for their vibrant colors and smooth application, allowing artists to create rich textures and layers. Unlike traditional chalk pastels, oil pastels do not smudge easily and can be blended for various effects. These versatile tools can be used on a variety of surfaces, including paper, canvas, and wood. Artists appreciate oil pastels for their ability to produce both fine details and broad strokes. They are popular among both beginners and professionals for their ease of use and expressive potential.
