Thanks Mickey and Blammer.
I was thinking the same about the teflon, and am afraid of the aluminum. I do have a turkey fryer for the heat source so I'm thinking I would be good there. I think I've already realized that mixing alloys in 8 to 10 pound batches will play heck with my consistency, and want to do that in 50 or so pound batches. I do have a Lodge dutch oven that I reserve for gumbo and chili and such but just can't bring myself to use it for lead.

Thanks again guys, and the obsession continues!
Rick
