Abstract: A process for melting at least one mineral material in powder form includes using at least one laser beam (12) for supplying the energy necessary to the melting, and gradually supplying mineral powder to a zone (10) that is impacted by the laser beam(s) so as to obtain the largest surface possible for interaction between the material and the laser beam(s).
