Summary

Shrinkage, sintering, softening, and melting of frits and glazes during firing can be observed. Measuring critical temperatures, contact angles, and other parameters makes possible the evaluation of glaze suitability under given firing conditions only when the heating rate of the equipment is close to that of industrial firing cycles. The behavior of frits and glazes changes drastically, especially in the fast firing processes (monoporosa, single fast, and double fast firing in the ceramic industry). The innovation presented in this work permits us to give an appropriate interpretation of physical parameters that was not possible in the past.
