I am looking for information on bonding or sealing of glass to glass. =
The glass parts come in the form of polished flat substrates, and can be =
as thin as microscope slides or as thick as photomask blanks (0.90 =
inch). The bond should be direct--I would like to avoid using bonding =
films or adhesives. However, glass-based bonding layers which can be =
deposited on one or both of the glass substrates would be alright. The =
bonding can be done at any temperature provided the glass parts are not =
deformed or distorted. The glass can be any of the commonly available =
commercial glasses such as soda-lime, borosilicate, or even fused =
silica. I would appreciate any information or leads.=20
