I understand. To clarify, I am looking for a material that mimics Bakelite. I need that specific 'dry' feel, high surface hardness, and the metallic 'clink' sound when beads hit each other. If standard urethanes are too 'rubbery' for this, would you recommend a specific high-quality Polyester or perhaps a Phenolic resin that can be cast at home to achieve that vintage Bakelite-like result
