DO NOT USE AN ALUMINUM POT TO MELT LEAD!!!
I can't say that strongly enough!
Use ONLY steel or cast iron.
Aluminum is, over time, SERIOUSLY weakened when lead is repeatedly heated in it. The thinner the aluminum, the more quickly the weakening happens.
More than one person has had the bottom come out of an aluminum pot while it has been filled with molten lead.
You have absolutely NO idea when it will happen.
