In a 4-1/2 qt Dutch Oven over a propane single burner I brought a 15.3 lb piece of pure lead to 625 F. I fluxed with Marvelux and skimmed off the dross. I made sure it was 625 F and added my .2 lb of Tin, stirring for several minutes. Didn't seem to mix too well. I then brought it up to 725 F for the Super Hard and again, added Marvelux. With a thin layer of flux on the surface, I gently settled in the numerous pieces of Super Hard (1.5 lbs) so they would get coated with the flux. For several minutes I kept stirring, getting the temp up to about 750 F. Seemed to be a huge mess with irregular chunks on top. I'd been smelting CWW much of the day and was tired so I turned off the heat and walked away for the day.
What did I do wrong? How can I fix the current mess and what do I do differently next time? My goal, using the Lead Alloy Calc is a 11.4 BHN mix. I used a Lyman lead thermostat.
