Abstract

A method for making glass ceramic composite structures, wherein a first and at least a second glass component, with an intermediate layer of a joining solder consisting of glass placed between them, are assembled to form a raw composite structure, wherein the joining solder has a radiation absorption capacity higher than the components to be joined, and wherein the raw composite structure is irradiated with energy, for example IR energy, at least in the area of the joining solder until the joining solder has softened sufficiently to bond together the components and the joining solder to produce a composite glassy structure. Thereafter a ceramization treatment is performed.
