Ceramic Fusion Molds Create dimensional ceramic and glass art in the form of a fish, gecko, dragonfly, and more. Paint the ceramic form with enamels and fill the cavities with frit. Upon firing, the glass will adhere to the ceramic form, but will "craze" as it attaches to the ceramic, resulting in an appealing crackled glass look. Available in numerous styles; cross, butterfly, gecko, fish, tree frog, love box, "welcome" plaque, dragonfly, a simple frame, and Christmas tree.
