Skullduggery has been molding and casting artifacts for over 30 years. We have crafted museum quality molds and casts of rare fossils from some of the most famous museum collections in the world. During this time, we have worked with many different molding and casting mediums: silicone, latex, alginate, resin, polycarbonate, urethane, plaster, gypsum cement, and others. Some materials are easy to work with while others are more problematic and require extra patience and expertise. To simplify things for novice mold and cast makers, our master mold makers have formulated the Perfect Series of molding and casting materials. This series consists of safe, easy, and reliable powders, that when mixed with water, produce high quality molds and casts.
