It's curious. Bismuth is really a heavy metal right there with lead. It also uses cyanide. It also wants to use stannic, not stannous oxide which is an opacifier and not a reducing agent.

Honestly, I think black tin will yield better results. Bismuth also is not cheap. If anyone tries it, let us know.
