With the proper release, you can cast Alumilite into almost anything. Here are a few examples: Silicone, Wax, Non-Sulfur Clay, Urethane, Latex, Plaster, Steel, Aluminum, and Wood. Thick paste wax or the Stoner Urethane Mold Release is required for non-silicone based items. If the mold is not made of silicone, the Alumilite resin is more than likely going to bond to it. So make sure the mold surface is not porous (cloth, wood, etc) and that you have an adequate layer of paste wax and/or Stoner on the mold surface.
