Abstract
A method is described comprising the steps of modifying a natural article to a predetermined configuration, making a mold of at least part of the modified natural article, filling the mold with a castable material to produce a reproduction of at least part of the surface of the modified natural article, modifying the reproduction to a predetermined configuration, making another mold from the modified reproduction and filling this mold with a castable material to produce another reproduction of at least part of the surface of the modified natural article; the second mold can be used to produce reproductions in commercial quantities.
Claims14
A method for making a cast reproduction that replicates on at least part of its surface the surface of a modified natural article, said method comprising the steps of:
- modifying at least part of the surface of said natural article to a predetermined configuration to produce a modified natural article,
- making a first flexible mold that replicates at least part of the surface of said modified natural article,
- filling said first flexible mold with a first castable material to produce a first cast reproduction,
- modifying said first cast reproduction to form a master cast reproduction, making a second flexible mold that replicates at least part of the surface of said master cast reproduction,
- placing said second flexible mold in a closable support structure, and
- filling said second flexible mold with a second castable material and closing said support structure to produce a second cast reproduction of at least part of the surface of said second flexible mold.
A method for making a cast reproduction that replicates on at least part of its surface the surface of a modified natural article, said method comprising the steps of:
- modifying at least part of the surface of said natural article to a predetermined configuration to produce a modified natural article,
- making a first flexible mold that replicates at least part of the surface of said modified natural article,
- filling said first flexible mold with a first castable material to produce a first cast reproduction,
- modifying said first cast reproduction to form a master cast reproduction,
- making a second flexible mold that replicates at least part of the surface of said master cast reproduction,
- filling said second flexible mold with a second castable material to produce a second cast reproduction of at least part of the surface of said second flexible mold, and
- making additional flexible molds by using the second cast reproduction as a master reproduction.
A method for making a cast reproduction that replicates at least part of the surface of a natural article, said method comprising the steps of:
- making a first flexible mold that replicates at least part of the surface of said natural article,
- filling said first flexible mold with a first castable material to produce a first cast reproduction,
- modifying said first cast reproduction to form a master cast reproduction,
- making a second flexible mold that replicates at least part of the surface of said master cast reproduction,
- placing said second flexible mold in a closable support structure,
- filling said second flexible mold with a second castable material and closing said support structure to produce a second cast reproduction of at least part of the surface of said second flexible mold.
