<p>A vacuum insulating glass (IG) unit and method of making the same. At least a first edge seal portion (51, 52) is provided on at least one of two glass substrates (33, 35) prior to tempering. When the substrate(s) are thermally tempered, the high tempering temperatures achieved cause the first seal portion (51, 52) to diffuse into or bond to the substrate (33, 35). Thereafter, after substantial cooling of the substrate(s) (33, 35) and during assembly of the vacuum IG unit, a secondary heating is performed to form a hermetic edge/peripheral seal using at least the first seal portion (51, 52) (additional seal material(S) (54) may be applied in certain embodiments before the secondary heating step).</p> |
