The photoelasticity is more suitable for crystalline-based and amorphous materials (Nielsen and Pyrz, 2002 ).

As such, two variables of state arise: the tensorial angoricity ($\hat{\alpha}$) and a new temperature-like quantity associated with the force-tile area which we name {\it keramicity} ($\kappa$).
