Crosslinked silicone foams are provided that can be substantially free of chemical blowing agents or byproducts thereof. These foams can be prepared from polymerizable silicone compositions that include an MQ-water cluster including a silicate MQ resin and a quantity of water dispersed in the silicate MQ resin and a silicone fluid, wherein the MQ-water cluster and silicone fluid collectively provide a inverted emulsion having a continuous and a discontinuous phase, the continuous phase including the silicone fluid and the discontinuous phase including the MQ-water cluster. The foams can be made by dispersing water into a silicate MQ resin to provide an MQ-water cluster; dispersing the stabilized MQ- water cluster into a silicone fluid to obtain an inverted silicone emulsion having the MQ-water cluster as a discontinuous phase and the silicone fluid as a continuous phase; foaming the silicone emulsion by evolving the water in the MQ-water cluster to provide a cellular structure; and polymerizing the silicone emulsion.
