ABSTRACT:
A method of making a cut glass panel comprising a plurality of glass piece arranged with cames in a predetermined pattern between adjacent edges of the glass pieces and having flanges on both sides of the glass pieces. The method comprises providing a mold having grooving in the upper face thereof 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 glass pieces, 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 and with the spaces between adjacent glass pieces above the grooving. Moldable material is introduced in the spaces to fill the grooving and the spaces. The previously formed flanges are positioned on the upper surface of the glass pieces so as to engage the moldable material at the top of the spaces. The moldable material is allowed to set so as to form the flanges on the other side of the glass pieces and the webs of the cames and to bond the flanges on one side of the glass pieces to the cames, and the completed panel is removed from the mold.
