A pearlized plastics mosaic article having a ceramic glaze thereover is made in a mold having a deep etched pattern of engravings to provide a relief casting having a pattern of grooves simulating the look of mosaic tiles. An ornamental mosaic finish is obtained by casting mosaic and background layers of thermoset materials. For contrast and definition of the mosaic ornamentation, the thermoset layers are cast of materials having different color pigmentations and material textures. In the molding process, the first thermoset layer is cast to a depth which is less than the height of mold engravings. After curing the first layer to a gel consistency, the second background layer of thermoset material is cast in overlying relation to the first thermoset layer and mold engravings. The thermoset materials are then cured and demolded to provide an integral mosaic casting.

Mosaic artwork including a decorative motif, manufactured by a casting method employing a mold having a mosaic pattern of engravings which define mosaic tile cavities and the decorative motif, the mold cavities including base surfaces which have spherical depressions which provide a pearlized relief casting finish, comprising the steps of: (a) casting a first layer of thermosetting material in the engraved mold, the first thermosetting layer having a depth less than the height of the mosaic pattern mold engravings; (b) curing the first mold layer to a gel consistency; (c) brushing the top surfaces of the first thermosetting layer to remove surface films formed in the curing process; (d) casting a second layer of thermosetting material in the engraved mold, the second layer having sufficient depth to overlie the mosaic pattern mold engravings, the second layer also having a different coloration from that of the first thermosetting layer; (e) positioning a strengthening member on the exterior surface of the second thermosetting layer; (f) curing the first and second mold layers to cured strength; (g) demolding the thermoset materials to provide a relief cast having distinct mosaic style impressions, decorative motif, and pearlized ornamentation of the mold; and (h) applying a porcelain glaze to the front surface of the demolded casting.
