Oil pastels are a type of art medium made from pigment mixed with a non-drying oil and wax binder. They have a creamy texture that allows for smooth application and blending, making them popular among artists of all skill levels. Unlike traditional chalk pastels, oil pastels do not require a fixative, as they are less prone to smudging. These pastels come in a variety of colors and can be used on different surfaces, including paper, canvas, and wood. Artists appreciate their versatility, as they can be layered, mixed, and even used with solvents for unique effects.
