I Broke My Bone Today

No, not a real bone, but a fake one. Today I tried out making a chicken leg out of Premo for 'The Hole', but it didn't work out too good. I was really testing out a new way of baking clay things so that they wouldn't get scorched like they had in the past. I did this by placing the item in a pile of cornstarch in a foil box which then went into my toaster oven. After I baked the perfect bone, however(I baked the bone then applied the meat), I accidentally cracked it while trying to clean it off and give it a little sheen by rubbing it. I applied the meat to the bone afterwords and then baked that. When I took that out I found that the meat had cracked and the bone broke completely. It would probably be salvageable, at least the bone part, but the meat isn't looking quite as I would like it to and I may give it another go later on. At least I know that baking it cornstarch works pretty well. I'll still need to test the original Sculpey in it though because that's the clay that burnt or turned purple all the time for me.
