In etching, acid-resistant coating containing petroleum jelly or tallow to prevent it from hardening when dry, so that textures can be impressed into it. It produces prints that have a softness of line and a grainy character suggestive of crayon strokes or of the grainy lines characteristic of a lithograph or a crayon-manner print.

An etching technique in which the plate is covered with a ground containing wax soft enough to be removed by pressing something into it. This can be anything textured, but paper is most often used. The paper is laid over the waxed plate and pressure applied with a pen, pencil, crayon, or fingers so that the wax is transferred to the back of the paper, exposing an area of the plate that when etched will produce a line with the texture of the paper. The line is softer and grainer than a traditional etched line.
