Abstract
Abstract A method for producing copies of natural objects including the steps of applying an electricity-conducting coating to a specimen natural object, electrolytically plating a metal shell about the object, attaching auxiliary mounting or fastening element to said object either after or before said plating step, development of a flexible mold element on the surfaces of the plated natural object, and subsequently utilizing said flexible mold in connection with conventional casting operations to obtain one or more copies of the natural object. Fine features of the natural object are simulated by separately applied components or decorations.
