    Try putting it in the freezer for 10 minutes, then slapping on a hard surface. With any luck, your castings will come out.

    Tried that. It was a No-go. 🙁 Ended up having to take a hammer to the whole thing to get the castings out. Now I need a new mold too. Oh well, that’s what happens when you forget important steps.
