Spritz distilled water onto metal clay powder. Mix with a metal knife and sturdy bowl, pressing against the sides of the bowl to really squish the water into the clay.


Add water slowly! As it hydrates, the clay will start clumping together. When most of it is moist – not wet – then you’re ready for the next step.


Roll the clay between the layers of a sheet protector or other plastic surface (use a tiny bit of olive oil to prevent sticking). When the clay is ready, it feels kind of like silly putty, and stretches and drapes without cracking.

ready to use clay

Roll the clay to desired thickness and cut out shapes, or create whatever you’d like. Cinter Metal Clay is now ready to play!


Once you’ve cut and textured your pieces, place them on a heating tray (mine is a retro monstrosity from Goodwill) to remove all the moisture. Once they pieces are dry, you can sand/file and refine as needed.


The next step, now that the water is gone, is to remove the binder. This can be done in the kiln, but I prefer using my camp stove – it is much faster! It only takes about 5 minutes. The dark pieces on the left are ready to go in the kiln. The pieces on the right are waiting their turn for binder burnout. The color change is important – if your pieces don’t smoke/start changing color in 5-10 minutes, your heat source is probably not hot enough.
