Creating Silicone Rubber Mold

I created a two-part silicone mold using my clay model as a master.I refined the surface of my clay model and made its details more distinct in preparation for the silicone mold. 

To create the first half of the silicone mold, I covered half of my clay model with softer white clay. This part required a rather delicate touch in order to prevent the two clays from merging with one another. The clay model is placed inside a box I constructed out of foam boards, and white clay is carefully added to the box until only half of the clay mode is visible.
