Scraperboard

Scratchboard or scraperboard is a technique where drawings are created using sharp knives and tools for etching into a thin layer of white China clay that is coated with black India ink. Scratchboard can also be made with several layers of multi-colored clay, so the pressure exerted on the instrument used determines the color that is revealed. Using scratchboard is said to yield a highly detailed, precise and sometimes textured artwork.
