What is scratchboard? This is a hard masonite clay-coated board that is sprayed over with black India ink. The subject is drawn on the surface from tracing paper is smeared with chalk using a pencil. Then it’s scratched by a xacto knife then an image of white appears on the board. The art is a result of white image on a black surface.

Scratchboard has an ancestry that goes back hundreds of years of scratching art first on animal bones and then on rocks and boulders. The medium is somewhat related to etchings and woodcuts. It’s not as popular as watercolor or acrylics but its making a good comeback.
