Abstract

A monolithic substrate of glass or glass ceramics and methods for manufacturing are provided, where the substrate has a lightweight structure. The lightweight structure includes recesses that are delimited by webs, such webs forming tetragonal or four-corner-shaped pockets. Due to the lightweight structure, the weight of the substrate can be significantly reduced, and at the same time a high rigidity can be ensured. The substrate can be used as a mirror support or a mirror and can be employed terrestrially and/or extra-terrestrially.
