Jackson's Carborundum Powder (silicon carbide) is an abrasive grit with a variety of applications. It can be mixed with water or oil to create graining and polishing pastes for metal plates or it can be used for carborundum printing.
Carborundum powder when adhered to a printing plate, inked and printed as an intaglio, produces very strong colour and tone. The powder can be applied by sprinkling it over PVA and the excess tapped off, or it can be combined with acrylic mediums and painted on.
