Mold Making

For a simple silicone mold, use OOMOO^TM 25 or 30. The materials are measured 1A:1B by volume mix ratio. OOMOO is a very flexible silicone mold material. It is pourable, it picks up fine details (you can read LEGO in the little round casts on molds where Legos(TM) are used as the pattern), the 25 is ready to cast out of in 2 hours, the 30 is ready to cast out of in under 7 hours. OOMOO is a very simple and forgiving first time mold making material.
