Copper ruby

Ran across this patent, they add a small amount of bismuth oxide to the formula. Anyone try this?

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.

The boro melters use it, I think. There's some stuff to learn from what they are doing.
