What is plasticity in ceramics?

Plasticity in ceramics refers to the ability of a ceramic material to deform and shape under applied stress without cracking or breaking, particularly when it is in a moist or softened state. This property is crucial during processes like molding and shaping, allowing ceramics to be formed into desired shapes before being fired at high temperatures. The plasticity of ceramics is influenced by factors such as the composition of the clay, the presence of water, and the temperature conditions during processing. Once fired, however, ceramics typically become rigid and retain their shape permanently.
