In this workshop, we will be using household materials to apply coloured coatings to titanium. Each participant will take home two titanium jewellery pieces – one simple strip pendant, and one 3D printed 'Bathsheba ball' (courtesy of CSIRO's additive manufacturing facility - Lab 22). Along the way we'll learn where the different colours come from, and how to control the conditions to produce the desired colour. "How to" notes will be provided for participants to continue their titanium adventures at home.
