ABSTRACT:
A method of making a window pane comprising a cut glass panel including a plurality of glass pieces and cames arranged in a predetermined pattern between adjacent edges of the glass pieces and having flanges on both sides of the pane. The method comprises providing a mold having grooving in the pattern of the cames, introducing moldable material into the grooving, allowing the moldable material to set in the mold to form the flanges for one side of the window pane, and removing the flanges from the mold. The glass pieces are positioned on the same or a similar mold with the edges of each glass piece spaced from the edges of the adjacent glass pieces in the predetermined pattern, the spaces between adjacent glass pieces being in register with the grooving. Moldable material is introduced in the spaces to fill the grooving and the spaces, and allowed to set so as to form the flanges on the other side of the glass pieces and the webs of the cames, the previously formed flanges for one side of the window pane being bonded to the window pane in register with the webs of the cames.
