Effect of a constant magnetic field on the mechanical properties of container glass

Most existing methods of strengthening glass alter the composition and structure of the surface layer. In addition, there are several serious manufacturing disadvantages. The results of treating container glass with a constant magnetic field under industrial conditions are reported. Thermomagnetic treatment increased the compressive strength of jars by 20-30% and the microhardness of the glass also increased. The basic advantage of this method is that it makes it possible to strengthen complex-shaped articles without altering the manufacturing and preserving the natural state of the glass surface. There is also no environmental pollution. 6 refs.
