Abstract

The present invention relates to a method for manufacturing a non-planar product in glass-ceramic. Said method comprises the following steps: (i) in a conventional furnace (3), heating a sheet of precursor glass of said glass-ceramic, so that said sheet becomes formable while avoiding its ceramming; (ii) forming said heated sheet; (iii) cooling said formed sheet (2b); (iv) ceramming said formed, cooled sheet.
