I cut an old 20lb propane tank in half (use the bottom half) , use it for my melting pot. I set it on a propane burner used for a turkey deep fryer. Works like a champ, I even throw in a little beeswax when I am melting the lead for flux to clean the lead with, after the beeswax is melted stir in with the lead, then just skim the impurities off the top. Dip the lead out with an old ladle and pour into a mini muffin pan that can be bought at the dollar stores. Get the ones with no Teflon coating. The mini muffins are the perfect size for your 10lb. pot. That's my 2 cents worth.
