| description | A method for constructing a mirror blank, including arranging hollow glass balls, on a front face sheet, and in close proximity to each other to permit fusing upon expansion; restricting the expansion of the hollow glass balls with a bounding structure during expansion of the hollow glass balls to force the hollow glass balls into a densely packed array of cells; applying heat to soften the hollow glass balls and increase the pressure within the hollow glass balls as the hollow glass balls fuse with each other during expansion, forming cells, wherein as a result of fusing, the hollow glass balls contact the front face sheet as a result of the increased pressure within the hollow glass balls; annealing and cooling the mirror blank to below annealing temperature associated with the hollow glass balls; and venting the cells. |
