The invention also relates to a process for manufacturing a bent glazing comprising a glass sheet comprising a peripheral compression belt and an orifice at least partially inside the peripheral compression belt said orifice having an edge compressive stress of at least 4 mpa and preferably of at least 8 mpa comprising the preparation of the glass sheet by the process according to the invention comprising the local cooling followed by the cutting of the orifice in the locally cooled zone.
Glass sheet bending process.
However glass rods and tubing is easy to bend and frequently done by artists and people working in laboratories.
Non isothermal processing of the glass with hot and cold areas within the glass sheet enables.
Bending a glass pane or bottle to a precise shape is not feasible without professional equipment.
At fraunhofer iwm glass bending processes have been developed for forming sheet glass especially with application of local heating.
All you need is a flame.
These processes have several advantages compared to conventional bending processes.
The process involves adhering two sheets of tempered glass in overlying relation and positioning a containment barrier such as vinyl sheets over the adhered.
