I have been making a variety of bismuth/tin sinkers, jigs and darts using Rotometal's Bismuth 281 that melts at 281 degrees with Do-It molds I use mold spray to prevent sticking. But when I tried making removable sinkers with Do-It #3172 mold, they completely stuck despite use of mold spray and I had to remove handles and put mold in 400 degree toaster oven to melt the bismuth out. Has anyone managed to make bismuth/tin removable sinkers without getting them stuck in the mold?
