Crayon etching works on the concept of resistance. When a water-based ink or tempera paint is used in tandem with a waxy crayon or oil pastel, a resist happens. This resist allows for the dried ink to be scraped, scratched or etched from the surface revealing the color of the crayon below. By scratching patterns into the prepared surface, the artwork is created. Crayon etching is a process that can be used by amateurs and professionals alike. A great deal of complexity can be created onto the surface in the creation of patterns.
The process of creating a crayon etching allows the artist to be creative in color and pattern creation. It also can be used to create a scratchboard type surface with a monotone color.
The artist begins by creating a simple line drawing in pencil.The preliminary drawing must be simple and not have any value. When patterns are created later in the process, the image becomes progressively more complex. A permanent black marker with a thick mark is used to go over the outlines of the drawing. The marker needs to have a relatively thick mark. This will aid in the process of scratching out the patterns. Next, the artist uses either crayons or oil pastels to color the image in completely. Special care should be taken to completely cover all areas of white as these areas will accept ink and prevent it from being scratched off later in the process. Ink is then applied over the colored surface covering the entire drawing completely. Using a foam brush will prevent any brush strokes from being noticed. After the surface is dry, a sharp tipped tool such as scratch board tool or a nail is used to remove areas of the ink with patterns. The ink will scratch off easily revealing the color underneath.
