Supplementum: which 'replenishes' or 'supplements'. Project started in 2019 in which the conceptual aspect of jewellery is central. In this research, both the object and the materiality are examined and questioned. From concrete to ice and precious metals to caramel. How is jewellery defined and does it know boundaries? This research has been an inspiration for the research question of the thesis  "De opkomende sieradendiscipline."
