Tempered glass is glass subjected to the procedure of hardening in a special furnace.
Glass hardening is the process of uniformly heating it in a special furnace to a specific temperature (usually up to 600-700 C) followed by forced two-way convection of air on both sides. After this procedure, mechanical stress occurs on the surface of the glass, which gives the glass an increased strength under mechanical stress (5-7 times compared to conventional glass), high-temperature resistance (resistance to rapid changes in temperature), and safety (when broken, tempered glass is divided into a large number of small pieces, which are almost impossible to hurt).
It is virtually impossible to distinguish between tempered and non-tempered glass by appearance. Only a person who has worked with glass for a long time and is familiar with the technology and hardening procedure can use additional devices to distinguish between tempered and unhardened glass by appearance without breaking. Until recently, there was practically only one testing glass method for hardening and its quality - destruction. Unhardened glass splits into irregular segments when broken. High-quality tempered glass breaks into many small (depending on the thickness of the glass) uniform fragments.
Now, special devices can detect altered properties of the glass surface not visible to the naked eye, but these devices are costly.
After tempering and acquiring the properties described above, glass is usually not subjected to any treatment because of its high strength and brittleness at the same time. In this regard, all work (cutting, edge processing, drilling, technological cutouts) is performed on the so-called "raw glass," and the final operation is hardening. The range of material applications with such unique characteristics is extensive: production of windows, doors, partitions, furniture, shop windows, roofs, cladding facades of buildings, automotive glass production, etc.
Today, tempered glass is very often used in insulating glass units, triplex, and single glazing to give products extra durability and safety. For example, it is possible to make glazing unique in its characteristics if you use energy-saving tempered glass. You get a solid and safe glazing that will also perform energy-saving functions, saving you money.
StekloMir LLP performs glass hardening, as well as painting with subsequent glass hardening. Production workshops are equipped with a furnace for tempering glass - North Glass (China) and a Rollmac Multigiass line (Italy) for painting with colored enamels. All equipment works non-stop in several shifts. Availability of high-tech equipment for glass processing and the continuous production process allows us to fulfill orders from significant construction and manufacturing companies.
