A Hobby Lobby just opened in our state. I want to make my own silicone mold. There is something by AMACO, it's mix a mold. It says that it is non toxic. Would I be able to us this?

You can try RTV-22 at http://rawmaterialsuppliers.com/product/rtv-22-22-durometer-half-gallon-kit-4-pounds-11-mix/ many use it for that application. There is a letter from universities saying to bake it and its food safe.
