OIL PAINTING MATERIALS. To get started you need oil paints, brushes, a place to mix your colors, a tool to mix them with and a surface to paint on. Plus you want a way to clean up. The ingredients are easy to find and you don't need a lot of them. You can do a lot with a little. Good brushes and good paints are easier to use and go farther than the cheap ones.
The medium is what makes the picture, sculpture etc. Oil paint is the commonest medium in painting, but there are also acrylic, tempera, crayon, ink, watercolor, etc. A sculpture is often made of marble or bronze, which is the medium of the work. Modern art also uses other media as e.g. video.
