Now you can make your own molds with the Castin Craft EasyMold silicone putty. This two part putty is ideal for a wide range of impression mold applications, including resin, epoxy clay, wax, soap, chocolates, ice cubes, plaster, air dry clay, low melt metals like metal clay and concrete. Once mixed, you have 3 minutes of working time with the putty and a 25 minute cure time. Once cured, the mold is strong, flexible and reusable. It is self releasing, so no mold release agent is required. There is no shrinkage and it has a high heat range, up to 400 degrees Fahrenheit. Complete instructions for use are included with the putty.
