1. A method of manufacturing a flush vehicle glazing, comprising the steps of:
providing a vehicle glass sheet which comprises at least two adjacent sections of a vehicle glazing area;
heating the vehicle glass sheet at a predetermined temperature T1 for a predetermined period of time t3 for bending the vehicle glass sheet by a bending process, wherein the temperature T1 ranges from about a temperature at which the viscosity of the vehicle glass sheet is 1013.6 Pa·s to a temperature at which the viscosity of the vehicle glass sheet is 109 Pa·s and the time t3 is enough to impart a selected permanent curvature to the vehicle glass sheet;
cutting the bent vehicle glass sheet in said at least two adjacent sections of the vehicle glazing area along a cut line, wherein the cutting step is conducted inside a furnace, while the cut line of the bent vehicle glass sheet stands at temperature T2, wherein the temperature T2 ranges from about a temperature at which the viscosity of the cut line of the bent vehicle glass sheet is 1012.4 Pa·s to a temperature at which the viscosity of the cut line of the bent vehicle glass sheet is 109 Pa·s;
cooling the vehicle glass sheet after cutting.
