Not with a metal detector.....I was walking at my sisters house many years ago.Someone had thrown a bag of trash onto a vacant lot,and it had been spilled,torn open somehow.....In the middle of this what was presumed trash,was a nice little cast iron pot,about 5 inches in diameter,about 5 inches high,three legs,and a wire handle....I recognized it from some old treasure magazines:It was a lead melting pot,for melting lead for casting black powder bullets,for muzzleloading weapons.It was VERY rusty when I picked it up.I wire brushed the rust off inside and out,got me some RUST-OLEUM flat black paint,and to this day,I still have it....It sits in a windowsill in Marcias home as I write this,matter of fact......
