Internationally renowned glass artist Patty Gray has partnered with Creative Paradise to bring you this Dam Mold to expand your creative boundaries. Create incredible glass slabs that are thick, consistent, and perfectly rounded; no need for coldworking. Use the finished slabs for roll-ups, drop rings, or to create thick slumped bowls. Mold creates a 10-1/2 inch diameter round slab, up to 7/8 inch deep. See size perspective of mold with quarter images shown. Mold must be elevated on kiln posts during firing; kiln posts sold separately. High quality ceramic mold can be fired many times. Coat with a casting primer before use.
