Scratchboard is a way of directly engraving an image. Each board is usually made up of three layers; a piece of masonite, a fine layer of dry white clay, and an even coating of black ink. A sharp tool is then used to scratch away the ink and reveal the white clay, creating an image from dark to light.

Every scratchboard artist has a different preference for how they scratch and what style they are hoping to achieve. In the videos below, you can see my technique of making thin hatch marks with an x-acto knife to create a soft and realistic effect.
