Tin cure Silicone. Mold Max 27 I believe.

Basic dump mold how to:

1.Glue item you want to mold to foamboard.
2. Create wall either out of clay or metal sheets. If your mold will be small enough, you can use a cup like I did :P
3. Mix Silicone and evacuate.
4. Pour Silicone at least from arm's length on the side of your board.
5. Wait 8 hours. :P

Let the silicone fill the void slowly, making it release any air bubbles that get trapped around your sculpture.

**DO NOT POUR PLATINUM SILICONE INTO TIN SILICONE**
