Scratchboard is a method of creating an image with contours scratched on paper previously covered with ink. The method is also known as waxography. This type of graphics began to be used in Russia in the 20th century. Wax or paraffin is first applied to thick paper or cardboard (you can also rub the surface with a candle) followed by a layer of ink. To avoid drops formation add some soap solution. After drying, the drawing is created with a sharp object (needle, knitting needle, knife or scraper). The bottom layer can be applied with coloured wax crayons. In this case, the picture will consist of coloured strokes. Scratchboard refers to non-traditional drawing techniques, it is often used to teach schoolchildren the basics of fine arts.
