This unique mold makes it easy to create pattern bars and thick fused glass. Simply layer glass slightly higher than the mold (glass will compress when firing) and fuse. Coat with casting primer before use. Durable ceramic molds from Creative Paradise can be used many times. Interior measures 8-1/2" x 2-1/2" x 1-1/4" deep. Step-By-Step: Pattern Bar Necklace Step 1. Cut up small pieces of your favorite glass or use scrap glass to create a base layer. Step 2. Use long strips of fiber felt (item#4824) to create the channels. Fill around the fiber with scrap glass. Step 3. Fuse in kiln. Use a tool like the Super Slicer (item#57108) to cut the glass into pattern bars. Step 4. Fire polish in kiln. Thread a necklace through the exposed channel.
