Another name for silicon carbide, carborundum is a abrasive substance sometimes used to build up the surface of a metal plate When the plate is pressed against dampened paper, the raised carborundum areas leave a craggy, relief impression on the paper The Catalan artist Joan Miro' helped innovate and popularize this process in the 20th Century For carborundum, see Miro', Espriu-Miro', and Robert Motherwell, The Cavern
> The trade name for silicon carbide, Carborundum began its use in printmaking as an abrasive which was used in effacing lithographic stones The particles, when mixed with glue, can also be used to draw on a plate-sometimes creating a raised surface-which is then inked and printed with the ink being held in the spaces between the particles The resulting prints are often textured due to the raised areas of the printing surface
