Hi I'm a chemist, my current work is with PFAS compounds, often known as forever chemicals. Please ask me about those, or anything else you are curious about related to chemistry. I will try to give you a solid response.

How do I remove lead when melting down scrap brass and copper?
some methoods use calcium to form a lead-calcium alloy that can be filtered.
but the method with the highest lead removal is vacuum distillation at molten temperatures since copper and lead have a huge difference in boiling point. if the target alloy is brass instead of copper you boil off the brass from the lead since it has a low boiling point compared to lead and copper (zinc contributes to this)
Could you expand on this? What is the end goal, cause that informs the process considerably.
I just want to melt scrap in my backyard without my castings giving me lead poisoning.
