I'm in the process of making a prop pocketknife with a blade made out of foam board (a sheet of foam sandwiched between sheets of paper) that pivots on a small wooden post contained in the handleThe handle is made out of polymer clay The easiest away to build the knife would be to bake it with the quot;bladequot; already in place.If I bake the clay at 275 degrees F and away from any metal bits (I use the polyfill in a pan method), what are the chances of my blade and the little post on the inside catching fire?
