ABSTRACT:
A decorative window consists of thick transparent plastic resin layer laminated to a sheet of glass. The outer surface of resin layer includes decorative features, such as deeply contoured pictographic images and finely detailed textured surfaces. The decorative window is produced as replica of a glass master originally made using conventional grinding and surface finishing techniques. The master is then covered with a mixture of silicone, catalysts for curing the silicone, and a light oil to form a mold. After curing, the mold is removed from the glass master, inverted and a glass sheet, which has been prepared for the process by being coated with organosilane ester, is clamped thereto. The mold cavity is then filled with a mixture of a clear plastic resin, catalysts for curing the resin, and organosilane ester. After curing, the replicated decorative window is removed from the mold.
