Abstract

A method for making duplicates of projectile points or other ethnic artifacts is presented. A two-piece mold of RTV silicone rubber is made over the object. Cold-cure acrylic, colored with dry pigment, is incorporated in the mold to produce a replica of the original artifact, in both color and texture.
