I am as unsure about the rest but i have a theory. one: in the preview for the next episode it shows they break the clay so whatever they need is IN it not on it. second: When they are in the car at the end Charlie and Sam almost forshadow that it is a weapon. Charlie stated it would be easier if there was a special sword and Sam gave her a look, a look that almost gurantees whatever is IN the clay is a weapon or way to find a weapon.
