What Is Carborundum?
Carborundum is a printmaking technique that uses gritty silicon carbide particles to create heavily textured printing surfaces capable of holding large amounts of ink. The process produces rich blacks, dramatic tonal areas, and strongly painterly effects that differ significantly from traditional line-based etching.
Artists apply carborundum grit to a plate using adhesives, varnishes, or acrylic mediums. Once hardened, the textured surface retains ink in deep recesses and irregular patterns, allowing for expressive tonal passages and dense atmospheric effects. The resulting prints often possess a physical presence and depth difficult to achieve through conventional intaglio techniques alone.
Carborundum printing became especially associated with experimental printmaking in the twentieth century, when artists sought alternatives to highly controlled engraved line work. The technique is particularly effective for abstract compositions, gestural imagery, and prints emphasizing texture and materiality.
Collectors are often drawn to carborundum prints because of their velvety blacks, tactile surfaces, and dramatic contrasts. Depending on how the plate is prepared, the process can produce effects ranging from subtle tonal haze to heavily embossed textures. Many contemporary artists combine carborundum with etching, aquatint, or drypoint to expand the visual range of the print.
