Metal powders are added to resin to produce realistic metallic finishes in cold casting. The higher the addition of metal the better the finish but generally at the rate of 50 parts filler to 50 parts resin. For economy the powder can be added to the resin used for the outer surface only. When cured the main body can be filled with resin and a more economical filler such as talc. When removed from the mould it can burnished with wire wool and metal polishes. Different metal powders can be mixed before adding to the resin for creative effects.
