Yes, emax ingots can be re-used. take an investment ring with a base (100gm) and fill it up and let it set. Pull the base portion off so you have open end on both sides. This is your test sizer to make...See more sure your ground on ingot will fit when you go to press. I cut mine i half.
Next get an ingot of decent size and use a diamond coated grinding wheel that is super coarse from
Eagle Alloys. Walt Shrader will fix you up. These are the greatest for knocking down sprues and reshaping old ingots. Just be sure to grind all the reaction layer off and round the edges so it will fit
in the investment ring using your test ring. Steam clean the ingot, dry with compressed air, weigh to
make sure you have enough product. You will be surpised at how much you can press with so little.
everytime we devest, we mark the bottom of the ingot with a sharpie.Never had a problem. Years of using this.
Hope this will help
