ComposiMold PowerMold (1 ounce =0.7 cubic inches) PowerMold is a stiffer version of our regular ComposiMold. It works the same as ComposiMold, but some people prefer a stiffer mold for polymer clay casting or two part molds. PowerMold is reusable in terms of melting and remolding. If you want to change your mold, just remelt, re-pour, and remold. This dramatically lowers the cost of mold making and makes it very affordable with a lot less stress. Heat Remove the lid from thiscontainer and melt ComposiMold in the microwave. Start with short intervals as heating times may vary. Duplicate To make a mold, pour the ComposiMold over your original part that has been coated with mold release. Let ComposiMold solidify by cooling back to it's flexible and rubbery consistency. Remove the original part from your ComposiMold and pour or press in your casting material. Reuse With Composimold, many cast can be made with the same mold. When finished casting, ComposiMold can be continuously remelted and reused to make new and unique molds. Visit www.ComposiMold.com
