This is a new one to me.
I have always relied on the content of the linotype and wheel weights for the traces of tin and antimony.
Does anyone have any good (note Simple) ways of taking raw antimony and getting it into the alloy. I have picked up some from a guy off the "bay" and am looking into if and how it can be useful for me to use.
As I gain experience, I am finding myself looking for more ways to get the cost down.
