Infusing cold wax with oil paints creates rich textures and depth in artwork. The cold wax, usually made from beeswax, is mixed with oil paint to give a matte, velvety finish. Artists apply layers of this mixture using palette knives or brushes, allowing them to build dimensional surfaces. The wax allows for various techniques like scraping, sculpting, or incising, creating both smooth and rough textures. Cold wax medium dries faster than traditional oils, enabling layering and blending in a more controlled way.
