Mix 1:1 by volume to get great duplicate texture. Pot life is 1 minute with a 7 minute cure time at 72°F. Heat and colder temperatures can affect working time. Pinch off into 2 marbles of equal size. Then roll each one into a snake (doesn't need to be a good snake). Then take both and twist quickly for 5-10 seconds. Then quickly knead so that most of the marbleinzing goes away. It is okay to have some marbelizing. You want to do this in 30 seconds, so you have the remaining 30 seconds left to depress your button, or whatever piece it is that you are duplicating.

Whole Lotta Whimsy warranties the product for one month from time of purchase.Important - Elevated temperatures will drastically reduce the shelf life of silicone rubber. For example, silicone rubber stored at 80°F / 27°C will have a shelf life of about six months. Material stored at 100°F / 38°C will have a shelf life of about two months.
-if you wear gloves to mix, do not wear latex as it effects the mold putty
-occasionally the surface of the texture being made can imped success. You may need to seal it first with a polyurethane.
-heat can be applied to speed up the curing process when making molds
-if you are casting polyester, polyurethane and epoxy it is advisable to prevent mold degradation by applying a release agent first
