New Cast Magic® Pig Iron® Grey yields a metallic grey effect that looks like aluminum when used in combination with a black resin like Smooth-Cast® Onyx®.
As the following video demonstrates, it is used like the other metallic Cast Magic® powders. Dust a mold cavity or surface with a small amount of Pig Iron® Grey powder. Mix black resin and pour behind the coated surface. The cured casting has a dhimmering metallic surface finish.
