ABSTRACT:
A method for making a thermosetting polymer reproduction of an object preferably comprises the steps of modifying an original object such as an object found in nature (e.g., a stone or array of stones) or a manmade article (e.g., a carved decorative object) to a predetermined configuration, making a first mold of at least part of the surface of the original object, filling the first mold with a first thermosetting polymer material to produce a reproduction of at least part of the surface of the original object, modifying the reproduction to a predetermined configuration, making a second mold from the modified reproduction and filling this second mold with a thermosetting polymer material to produce a reproduction of at least part of the surface of the original object. The second mold can be used repeatedly to produce reproductions in commercial quantities.
