发明名称 Process of fabricating metal ornaments
摘要 A process of fabricating metal ornaments, such as, for example, jewelry pieces, is disclosed. The inventive process includes the steps of producing a design image of an object or subject, to be incorporated within the ornament, onto a first working medium by means of a camera lucida. A pantograph is then employed for reproducing the image, normally upon a reduced scale, onto another working medium, such as, for example, casting wax, in order to produce a working model of the design image. A master mold is subsequently formed by means of lost wax techniques, and the final metal ornament is produced by casting the same within the master mold.
