Dox Thrash (1896 – 1965) – Carborundum
Working as a print maker during the Great Depression, Dox Thrash invented a new technique for etching copper in 1937. His discovery, known as the carborundum process, became a standard practice among printers and print makers. This process involves using silicon carbide grit, which is sprinkled onto the plate before it is printed, creating a texture and tone that mimics the look of charcoal or pencil drawings. Thrash wanted to name the process “Opheliagraph” after his mother, Ophelia.
