All ceramics and clay contain metal atoms and oxygen atoms, which form metal oxide crystals. The heating process bonds the metal oxide crystals together as well as removes the water from the clay or ceramic. After heating, the ceramic or clay item is a solid piece of pottery.
What is ceramic clay made out of?
Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms.

Ceramic glass also expands and contracts less than tempered glass, but this isn’t usually a concern in the fireplaces and stoves people have in their homes.
Why ceramics are brittle?
Ceramics. Ceramics are generally brittle due to the difficulty of dislocation motion, or slip. There are few slip systems in crystalline ceramics that a dislocation is able to move along, which makes deformation difficult and makes the ceramic more brittle. Ceramic materials generally exhibit ionic bonding.

Why graphite and diamonds are different from ceramics?
Secondary bonds also are important in certain ceramics. For example, in diamond, a single-crystal form of carbon, all bonds are primary, but in graphite, a polycrystalline form of carbon, there are primary bonds within sheets of crystal grains and secondary bonds between the sheets.
