] 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.
