Use this pallet knife for hydrating your metal clay. I recycle my metal clay dust, and pieces I don't want to fire. First I grind un-fired metal clay in a coffee grinder. Then I place the ground metal clay onto a plastic report cover. Spritz the metal clay with distilled water and fold the water into the clay using this pallet knife. Roll the metal clay out very thin. Spritz it again and fold it over forming it into a ball. Roll out thin again. Repeat the process until the clay is a consistency you like.
