Soap ground is also called white ground. Like all grounds, it is a way of protecting portions of a plate from acid. Soap, however, is imperfectly acid-resistant and the acid penetrates it in varying degrees. You draw with a paste made of soap flakes, linseed oil and water, and usually add an aquatint to provide tooth. The image is essentially white against a dark background.
