Invented in 1891 by Edward Goodrich Acheson, silicon carbide or carborundum was created by electrically fusing a mixture of clay and carbon. Carborundum is a strong abrasive that can scratch glass and easily polish and cut metals. Depending on the function, few adhesives are strong enough to bond carborundum to steel because the friction created during polishing between the object being polished and the carborundum is usually greater than the holding power of the glue. If you are uncertain about the characteristics and capabilities of a specific adhesive, contact the manufacturer for details. Carborundum is also frequently used in printmaking to create fine textures in metal and bonds easily for this function. Purchase glue, sealant or resin from local retailer or online source. Put on protective gloves. Mix carborundum and adhesive in a metal cup with spoon. Follow any proportion directions or step-by-step instructions listed on adhesive label.
