A. B. Belyakov and V. S. Bakunov in [1] touch upon the
extremely important problem of reproducibility of the quality
of ceramic products. However, this problem is as significant
for all high-melting nonmetallic and silicate materials.
In view of that, the concepts discussed in the above paper acquire
a fundamental and conceptualistic nature for the field
of technology. While largely sharing the views of the mentioned
authors, we, however, believe that the concept of the
instability of quality as a consequence of the probabilistic nature
of the processes is not quite adequate to the actual situation.
