1. A method of making a glass laminated structure comprising:
- retaining first and second glass panels against first and second platens, respectively, and in spaced generally parallel relationship using differential fluid pressure acting across said panels;
introducing a curable flowable material into the space between said panels during said step of retaining;
curing the flowable material to provide said glass laminated structure; and
said first glass panel and the first platen have confronting faces of somewhat different configurations and said step of retaining holds the first panel against the first platen with sufficient force to deform the first panel to more closely conform the face of the first panel to the face of the first platen to improve the optical characteristics of the laminated glass structure.

Abstract
A method of making a glass laminated structure comprising retaining first and second glass panels against first and second platens respectively, using differential fluid pressure. The panels are held in spaced, generally parallel relationship and a curable flowable material is introduced into the space between the panels. The flowable material is then cured to provide the glass laminated structure.
