ABSTRACT:
An automotive back window for flush glazing is manufactured by subsurface scoring a glass sheet to define an automotive back window blank in the sheet surrounded by sheet supporting glass portions. An endless band of ceramic paste is silk screened over the score as screen portions beyond the screen pattern are supported by the supporting glass portions. The sheet is thereafter baked to remove volatiles in the paste, the supporting glass portions removed from the blank and the blank having the baked pattern is bent and/or tempered.
