I am looking to build/buy a propane smelter. For a propane burner how many btu's is enough?
I see some small single burners around 17K btu ($40) ,some heavier burners around 30k btu, and then fish fryers around 75k btu.
I would like to have a slower melt because I can catch any zinc ww that I missed in my sorting.
I mostly have coww in a cast iron pot. I currently use a gas Coleman camp stove.
What do you reccomend in a smelter that is strong enough to support the weight of 30-40 lbs. Of lead?
