| description | The process comprises introducing a green glass blank (10) in a temperature state in which its viscosity enables a deformation, and molding the green glass blank on a curved support surface (23) of a molding tool (20). The green glass blank is: molded on the support surface during the remolding process using a movable blank-holder (25); deformed in the region between the blank holder and the support surface and by two oppositely traversed blank holder; ceramized after its deformation; and provided with a decorative coating and/or a functional coating before its transformation. The process comprises introducing a green glass blank (10) in a temperature state in which its viscosity enables a deformation, and molding the green glass blank on a curved support surface (23) of a molding tool (20). The green glass blank is: molded on the support surface during the remolding process using a movable blank-holder (25); deformed in the region between the blank holder and the support surface and by two oppositely traversed blank holder; ceramized after its deformation; and provided with a decorative coating and/or a functional coating before its transformation. The blank-holder is: moved along the curved support surface during the remolding process; unrolled by rollers on the green glass blank; moved into a final forming position in which it rests on the deformed green glass blank; and kept in the cooling phase of the green glass blank formed glass or glass ceramic mold part in the final forming position. An independent claim is included for a glass- or glass ceramic-mold part. |
