Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method of manufacturing a bent glass ceramic panel having a determined bending radius with no stress and strain by bending a semi-finished glass panel to be ceramicized, and to provide a device to practice the method. SOLUTION: This method of manufacturing a bent glass ceramic panel comprises the steps of bending a semi-finished glass panel in a heating chamber of 10 to 50 deg.C higher temperature than the transition temperature of the semi- finished glass panel to be bent, annealing the main body at room temperature at applying a determined curvature derived from the geometrical shape of the main body, attaching the semi-finished glass panel to the main body, heating additionally the bent region of the semi-finished glass panel, and ceramicizing the bent semi-finished glass panel by an ordinary method.
