Silicone is a material made of polymers, frequently used in sculpture and for making theater props. Silicone is as resistant as glass and as versatile as plastic materials, and is also lighter than clay or metal sculptures, so it presents many advantages for sculptors and scenographers. Silicone can be used to make hyperrealistic sculptures that have a life-like appearance. The making of a silicone sculpture involves the use of a mold, which you can make based on a model or a prototype or purchase.
Things You'll Need
- Mask and gloves
- Cornstarch (optional)
- Liquid silicone
- Bowl or bucket
- Wooden stick or spatula
- Propanol alcohol
Clean the inside of the mold using a wet sponge and allow to dry.
Tape the elements of the mold together. Most molds come in two or several pieces, which you can take apart when the silicone is cured.
Prepare the silicone rubber in a ceramic bowl, or a bucket if your mold is larger. Mix the two silicone rubber compounds in a one-to-one ratio using a wooden stick or a spatula. Obtain a homogeneous liquid, and break any bubbles from the surface of the liquid using a cutter or a sharp object.
Pour the liquid silicone through the cavity that is located on the top of the mold. Tap the sides of the mold to remove air bubbles. Break any bubbles that surface.
Allow the silicone to cure for 24 hours.
Cut the tape that holds the mold together, and remove the mold from around the sculpture.
