Advanced Techniques
The next step in moldmaking. These videos and step-by-step tutorials show techniques which are for advanced users and include cavity molds, multi-part molds, and other ways to mold complicated originals. Whether you are interested in reproducing a sculpted figure, an antique picture frame, an industrial pattern, an architectural molding, a fossil, animal skin (taxidermy), the texture of a piece of fabric, or a toy, you start by making a rubber mold. Whether you want to make one or one thousand reproductions of an original, you can do it using a mold. Whether your original model is made from clay, wax, plaster, sand, concrete, stone, metal, bone or almost any material, making a rubber mold makes it possible to reproduce that model – exactly.
