A scratchboard is a drawing surface used in art made of a board coated with a layer of traditionally black ink or clay, though it can be any color, covered by a contrasting white or colored layer. Artists create detailed images by scratching away the top layer with a sharp tool or blade, revealing the color underneath. This technique allows for delicate line work and high-contrast images. Scratchboard is commonly used for illustrations, detailed drawings, and creating textures and patterns. Some scratchboards have different colored backgrounds or multiple layers of color, offering a wider range of effects and artistic possibilities.
