How Do You Make A Plaster Mold For A Mermaid Tail?
Making a cast of a mermaid tail sculpture starts with making a mold, or negative, of the sculpture. The most common type of mold is made from plaster, a mixture of gypsum and water. This type of mold is ideal for casting in plaster, latex, rubber and other materials, the choice of which will depend upon whether you are making your mermaid tail copies as artistic or costume pieces. Follow a few simple directions to make a plaster mold for your mermaid tail sculpture. Place your finished mermaid tail sculpture in a protected work area. Make sure that all of the finishing details are on the sculpture, such as scale work and other sculpted designs. Spray the sculpture with Krylon Crystal Clear or another clear sealing spray so that it holds the details better. If you are working with solid, dried clay and not soft plasticine, coat your sculpture with Vaseline. Let the coating dry completely. Determine the center line of the piece, going from the tail top, around the fin, to the other side
