I'm assuming something this large is needed when smelting pounds and pounds of wheel weights .. Also I'm seeing that tea candles are being used or beeswax as the flux agent..
Any help will be appreciated.
Scrap lead is scrap and will have all kinds of 'stuff' (I cleaned that up) in it. If you have a 'bottom' feed pot, that 'stuff' is bound to plug it. I have an old electric Lee pot that I pre-melt in. After melting and fluxing, I use a dipper to fill ingot pans. When done, I dump the little pot and all kinds of 'stuff' is or was in the bottom.
For fluxing material, paraffin used for canning is cheap and readily available.
Watch out for water (any water), flux well before cleaning the dross from the top of your melt, don't loose the tin.
Lead is lead is lead but there is some additives that have been put in some of it that I have never been able to cast with. I'm not a metallurgist and don't have a clue what it or they are. My way around this was to pre-melt the little pot full, make a sample cast and if all went well good, if not, dump the pot and try to determine which types of scrap were the offenders (some of those flat with sickie back wheel weight as I remember).
Remember: ventilation and lots of it and protective equipment. Hot lead is HOT!
