Dave, in the interest of breaking the chain of
ad hominem exchanges: this illustrates that you don't know enough about the metallurgy of tertiary lead alloys to post about it- you need to research boiling points, vapor pressures; don't rely on hypothetical or anecdotal enthusiast site conversations without data. Working with clean alloys at the kitchen-oven temperatures involved, all you need to do is wash your hands afterwards.
If nothing else, you'll come out of this exercise better educated about the extent of the risks and how to mitigate them
