The primary disadvantages of ceramic materials include their inherent brittleness, low tensile elasticity, and susceptibility to shattering or chipping upon sudden impact against hard surfaces. Because they cannot bend or absorb shock like metals or plastics, they fail catastrophically under high tensile stress. Furthermore, heavy ceramic items can be cumbersome to handle, difficult to repair once broken, and prone to thermal shock cracking if subjected to extreme, rapid temperature fluctuations.
