This is a step by step tutorial of how to make a silicone mold. The items used are all household products.

Step 1 1 Place the sculpture on a bed of clay. The clay needs to cover ½ of the sculpture. If this were a plaster mold, the midline where the clay goes up to needs to be along the highest points with no undercuts. This is the surface you will make the first half of your mold on.



Step 2 2 Smooth the surface of the clay with a wet brush, then put four 1/4 " round 1" long pieces of clay on the bed to act as keys for the silicone. Put a piece of clay on the top of the sculpture to act as a pour spout (Sometimes the pour opening will be along the seam line. In that case, be sure to leave it open, never cover the pour hole)

Step 3 Put a thin layer of Vaseline on the clay bed and sculpture.

Step 4 4 (Read and follow warning labels on all chemicals) Mix 1/3 cup of silicone with 2 tbsp of rubber cement together in a bowl. Should have the texture of peanut butter.

Step 5 Spread the silicone on the clay bed and sculpture. Do not cover the top of the pour hole.

Step 6 Press 1 ½ square pieces of drywall mesh into the silicone. Notice that we did not cover the pour hole.

Step 7 Cover the mesh with a thin layer of you silicone mixture.

Step 8 Cover dry silicone with layer of Vaseline. Then mix plaster into a bowl with water, it should feel like pudding when correctly mixed. Then put a thin layer of mixed plaster on the Vaseline coated surface of silicone (do not cover pour hole).

Step 9 Check out dip 3x 2 bits of burlap in mixed plaster and place them on the plaster level from previous step. Usually do not cover pour hole. As the plaster is certainly wet still, lightly spray the top of burlap with h2o and erase the surface.

Step 10 Slice the clay bed clear of your work surface with something sharpened (by no means cut towards yourself). Start the mold and remove clay bed from sculpture. The clay in the key slots must be removed aswell. Clean any staying clay bits off.

Step 11 Cover initial fifty percent of the mold and sculpture with Vaseline (do not forget to place Vaseline in the keys). Repeat the whole process on this side now.
