What is the fastest way to cure silicone molds?

Heat (Platinum-Cure Silicones) – Elevated temperatures will reduce the pot life and cure time of platinum catalyzed silicone rubber. Many mold makers will use heat to accelerate the cure time (demold) of platinum silicone molds. Humidity (Tin-Cure Silicones) – Will cure faster in humid environments.
