Claims5
A method for preparing molds for use in making decorative, 360 degree elements taken from the group comprising lampshades, terrariums and lamp bases, comprising the steps of:
- preparing a hemispherical master form which reflects the desired shape and final form of the mold;
- applying a layer of formable, hardenable resin to said master;
- placing filamental wire on said resin layer to define a desired pattern thereon;
- applying a second layer of said resin over said filamental wire;
- applying heat and pressure to said master form so as to cause said resin layers to form integrally around said filamental wires causing definable, patterned ridges over the surface thereof;
- and,
- casting a copy of said patterned ridges by applying a thin, deformable plastic sheet thereon and applying sufficient heat and pressure to cause said plastic to form a copy of said patterned ridges therein, whereby a series of said copys can be used to form a 360 mold for use in preparing said lampshades, terrariums and lamp bases by the application of transparent materials cut to fit within said patterned ridges.
