A ceramic is an inorganic, non-metallic solid prepared by
the action of heat and subsequent cooling. Ceramic materials
may have a crystalline or partly crystalline structure, or
may be amorphous, i.e., a glass. As most common ceramics are
crystalline, the definition of ceramic is often restricted
to inorganic crystalline materials, as opposed to the
non-crystalline glasses.
