Answer:
clay
Explanation:
The first step in the manufacture of a sculpture in molten metal or other definitive materials is the making of a clay model of the desired piece. As in the molding technique, a clay plaster mold will be removed from the clay sculpture. This plaster mold will then be filled with wax, obtaining another identical piece in this material, which can be touched up, to correct some imperfections derived from the mold. From the wax model, the sculpture in final material will be made using the lost wax method. This method is the most used, because it produces parts with complex designs and better finish.
