Zwaar Metaal

April 2016 – Chladni figures printed with the Aquatint technique during the workshop ‘Zwaar Metaal’ at gallery Plaatsmaken: A plate is mounted on a speaker and covered with powdered rosin – depending on the frequency of the sound different patterns emerge. With controlled heating the rosin melts, being protected against the following acid bath. After colouring the plate it can be printed.
