Hardening
Glasses offered by us are subjected to modern horizontal glass tempering method, which leaves no traces of heat treatment. Hardening is to heat glass sheets to a temperature of about 700 Celsius degrees and cooling it with cold air. As a result of this process, stresses arise in glass structure, which significantly increases the strength of glass to impact. An additional advantage of tempering is to get through the glass safety features, as in the case of breaking glass breaks into small pieces with blunt edges.
