Abstract:

A method was developed for producing a glass called steklofon, the inner and outer sections of which have different degrees of hardness. Thus, when one section is shattered the other remains whole, keeping its transparency. The technique of producing steklofon involves the separation of its inner and outer sections during heating in an electric furnace and during air cooling, where they are subjected to different thermal treatments. For this purpose the inner section of the glass must be protected by a special shield or by some other method. A simple means of shielding the center section of the glass is to put a protective covering of kaolin and aluminum paint on its surface. Author
