â¢ OIL PAINTING (noun) The noun OIL PAINTING has 2 senses: 1. a picture painted with oil paints. 2. the art or method of painting with oil paints. Familiarity information: OIL PAINTING used as a noun is rare.
Oil pastel (also called wax oil crayon) 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.he surface chosen for oil pastels can have a very dramatic effect on the final painting. Paper is a common surface but this medium can be used on other surfaces including wood, metal, hardboard (often known as masonite), MDF, canvas and glass.
