Abstract:
1. A process for manufacturing a glass frit, the process comprising the steps of: melting a mixture of vitrifiable raw materials in powder form by using a laser beam to provide an amount of energy to melt the mixture, said melting step including placing the mixture in a hollow zone of a manufacturing device, directing the laser beam in a direction of the hollow zone so that an upper surface of the mixture in the hollow zone is impacted by the laser beam to create a melting mixture with a molten mixture of the vitrifiable raw materials obtained at an overflow of the hollow zone, while impacting the upper surface of the mixture with the laser beam, over an inclined plane continuously supplying the hollow zone with further vitrifiable raw materials in powder form, using an overflow located opposite the inclined plane, draining the molten mixture of the vitrifiable raw materials into a reservoir, cooling the drained molten mixture of the vitrifiable raw materials in the reservoir by quenching with a liquid in the reservoir to form a solid mixture of the vitrifiable raw materials; and grinding of said solid mixture of the vitrifiable raw materials to obtain the glass frit.
