Abstract
A method of forming an article from a glass sheet (20) having a glass-sheet bonding surface (24) and a glass carrier (10) having a carrier bonding surface (14). At least one of the glass sheet and carrier bonding surfaces is coated with a surface modification layer (30), and then the glass sheet is connected with the carrier via the surface modification layer. From the perimeter of the glass sheet and the carrier while connected, there is removed a portion of the surface modification layer so as to expose a portion (19, 29) of the bonding surface on each of the glass sheet and the carrier. The glass sheet and carrier are then heated at a temperature ≧400° C. so as to bond the perimeter of the glass sheet (26) with the perimeter of the carrier (16).
