Abstract: A method for fabricating a decorative window insert, and from the insert a decorative window, comprises the steps of producing a plurality of planar glass units each adapted by size and shape, for assembly together as a decorative insert master by assembling the planar glass units into a planar assembly wherein the planar glass units are joined by a came, producing a mold from the decorative insert master, the mold replicating the decorative insert master with a came mold portion and a planar glass units mold portion, filling the came mold portion of the mold with a dyed catalyzed resin and curing the resin as a simulated came portion of the insert, filling a planar glass units mold portion of the mold with a non-dyed catalyzed resin and curing it as a simulated glass portion of the insert followed by a post-curing of the simulated came portion and the simulated glass portion to produce the decorative window insert.
