The name "Rubbing Ink" is actually wrong, it is crayon in a tablet form. Rubbing Ink used as a type of shoe polish. With a piece of cloth the crayon is picked up and smeared on the stone. Rubbing Ink is ideal to use as a supplement to the chalk technique. Rubbing Ink will rarely be found uniquely on a print. It allows to make very subtle transitions and woolly tones. Used as a drawing crayon it allows to set up large surfaces. (Google translate) | |
