Bismuth in assay of gold and silver

[pablohdez3]

Hi guys I'm training as an Assayer and I found this great forum; I'm trying to find information about how the presence of bismuth in the assay of gold and silver can affect the dore bead? using the scorification process; so far I couldn't find anything on my text books or other papers.

Thanks.

Bismuth has been used as a lead substitute in the fusion process.

The buttons are very brittle.

I think you already read this in a different forum.

Thanks a lot, I knew that bismuth can substitute lead. But I didn't know that it can make the button very brittle.

Cheers.

By the way do you know about any other forums like this?
