From the Internet the melting of lead is at 621 degrees , The red hot coals of a wood fire are 3000 degrees . If i use a cast iron pot placed in a bed of red hot will my lead simply melt to a liquid that i will see - then to be pored in to a pottery planter I have and will just bust up when lead is cool . the lead i have are from plumbing joins - car weights and I also have 8 # from a battery that has been soaking and washed in backing soda .
