Abstract
An automotive window is manufactured by silk screening a pattern of a ceramic paste on a piece of glass having peripheral dimensions greater than the peripheral dimensions of the window. During the silk screening, portions of the screen extending beyond the pattern are supported by glass portions extending beyond the window to prevent bending of the screen near the pattern. The piece is scored through the pattern to define the window or a window blank within the piece and thereafter the glass around the window is removed. The window is then tempered at which time the ceramic paste fuses to the window.
