Things You'll Need
Clay or polymer clay in your choice of color (white works well)
Mask mold OR a friend's help
Kiln or oven
Paint and brushes (optional)
Ceramic masks can be beautiful additions to any home, and if they are made light enough, can even be worn for special costume events. The method offered here will allow you to make an entire face mask or one that only covers the eyes (this is the most suitable for wearing). Additionally, it is a fairly simple process, and you can paint the masks however you like, allowing you to create a truly unique piece.
Pull off a small handful of clay and knead it several times until it is smooth and pliable.
Form the clay into a ball and flatten it slightly. Roll the clay out to 1/8 inch or less.
If you're using an already-made mask as a mold, cover the mold with a very thin layer of petroleum jelly. If you choose to use your own face as the mold (this is only recommended for half-face masks that only cover the eyes and top of the nose), pull your hair back from your face and cover your face with a very thin layer of petroleum jelly, adding a bit more to your eyebrows to avoid sticking.
If you're using a mold: Lay the thin piece of clay over the mold, and smooth it into shape. Trim the excess clay around the edges of the mold, and then cut out the eyes. If you're using your face: Close your eyes and have a friend lay the thin piece of clay over your eyes and the top of your nose. Avoid covering your nostrils or mouth, and smooth the clay into shape. Have your friend use a PLASTIC knife to trim the mask to the appropriate size and then cut out the eyes.
Smooth the cut areas with your fingers, and ensure that the surface of the mask is as smooth as possible.
Allow the clay to air dry completely (if using a mold) or to stiffen hard enough to be removed without losing its shape (if using your face).
Remove the mask from the mold or your face, and gently wipe the petroleum jelly from the inside of the mask.
Harden the mask in a kiln (if using regular clay) or in an oven (if using polymer clay).
Paint or decorate the mask as desired.
DO NOT cover the entire face with clay, as it could suffocate a person.
