How To Make a Quick Silicone Wound Prosthetic

The original wound will be sculpted out of non-sulfur clay, on a plastic base.

To begin, place a small amount of clay on the base. Then create the detail of the fake wound by using a wooden tool. You can smooth the edges of the clay sculpt by using a cotton swab. Now, you can slice clay pieces that approximately 3/8" thick by using a metal scraper. Then cut the flat pieces into strips. Multiple strips will be used to construct a mold wall. Press the clay strips onto the surface of the platic base to create a water-tight containment field.
