Abstract
A method for producing a shaped body (10) made of glass or glass ceramics comprises the steps of: (a) placing at least two glass blanks (12a, 12b) side by side on a shaped surface (14) of a temperature-resistant sagging mold (13); (b) sagging the glass blanks (12a, 12b) onto the shaped surface (14) by heating the sagging mold (13) and the glass blanks (12a, 12b); (c) attaching the sagged glass blanks (10a, 10b) to each other in order to form the shaped body (10); and (d) lifting the shaped body (10) from the sagging mold (13). A shaped body (10) comprises at least two glass blanks (10a, 10b) attached side by side and formed by sagging.
