Uroboros‘ URO104 Noodles are approximately 17” (43cm) in length, and are packed in 5 oz (140 gm) tubes. Glass noodles are shaped like fettuccini noodles: flattened to approximately 1.35mm thick by 3/16” (4.5mm) wide. They are often used with dichroic coatings on them for dazzling lines of color. Since glass Noodles are much thinner than any sheet glass, they build up less thickness and weight in either fused or torch worked objects.
