well, pick your poison, cyanide or mercury. the presence of arsenic in glass will certainly knock you on your can. Volf declares that Mercury has no role in glass on the one hand and in the other refers to distinct color changes in batches where it's present. I have had it suggested to me that bismuth could replace lead in whole or in part but at that time the price of bismuth was over eight times the price of lead.
Bismuth is certainly used mixed with silver salts to help keep them from oxidizing away as a surface treatment but conditionally in its nitrate form.

I think pursuit of the Neri observations regarding mercury are worth pursuit. Dino Rosin gets really wild chalcedonia effects and he doesn't talk much about his formulations.
