I went out to the farm yesterday for my first big smelt of what I thought was 678 lbs of COWW (more on that later.. Aiming to smelt a batch of 98/2.
My pot is an old 12-qt Dutch oven. I measured it with water. I only managed 2 potfuls before getting low on propane (improvements to the fryer are coming.)
Each time I melted until I had 10 qts of clean, molten lead, which, if I understand specific gravity, should weigh about 230 lbs. Then added 5 lbs of pewter (each pot) and fluxed.
After finishing, I weighed the clean, alloyed metal, and it came to 313#.
I might have to go over this again, but I’m pretty annoyed at the prospect of having wasted 4 lbs of pewter. I guess the boolits should fill out well and be nice & shiny.
I’m going to re-measure the pot and do the math again before any further attempts.
I also weighed the remaining COWW and somehow came home with 70# more lead than I left with, despite leaving a can with about 35# of clips out at the farm.
