Making a conductive copper ink pigment | Files: Geek Out | Tags: art supplies, chemistry, copper ink, DIY, electrochemisty, electronics, experiments

This is part 1 of a project to DIY a circuit-writing pen: making a copper pigment. I thought I’d start with easy methods and readily available materials. This is a simple chemistry experiment suitable for classrooms, garage chemists and hobbyists. The pigment produced conduct electricity pretty well.
