Many people assume that because oil pastels contain pigment and a binding agent similar to paint, they behave like their wet counterparts. Similarly, while oil paints dry to a hard, flexible film, oil pastels retain a soft, buttery consistency.
Why Oil Pastels Stay Non Drying and Blendable
Because the binding agents do not evaporate or cure through oxidation in the same way paint does, the material remains somewhat flexible and waxy long after application. In reality, they occupy a unique space in the art world, acting more like a waxy version of colored pencil or crayon than a true liquid medium.
Oil pastels, thanks to their specific formulation, remain workable for much longer. Artists can scrape away layers, glaze colors, or smooth transitions long after the initial mark has been made.
Understanding Why Oil Pastels Remain Non-Drying and Blendable
On the positive side, the wax content allows for easy blending and reworking. This distinction is crucial for artists deciding on a medium for a specific project, as the "dry" nature of oil paint allows for glazing techniques that are impossible with the ever-tacky oil pastel.
