Asian 50mm Cobalt Blue Tubing
ACT-BTC50
Asian 50mm Cobalt Blue Tubing is heavily saturated transparent cobalt blue borosilicate tubing manufactured in China. This tubing comes in four-foot lengths and is sold by the piece. The deep, rich cobalt blue color maintains excellent transparency even in thick sections, making it ideal for large-scale work where you want the color to read with clarity and depth. The 50mm diameter provides substantial wall thickness and structural integrity for major hollow builds, sculptural forms, and production work where you want the visual impact of a bold, saturated blue.
Use 50mm cobalt blue tubing for large hollow builds, oversized components, and exhibition-scale pieces where the color and diameter work together to create striking visual presence. In lampworking, this size is excellent for creating large vessels, statement beads, and sculptural sections that demand substantial glass. The saturated cobalt blue pairs effectively with clear glass for high-contrast effects, with whites and light colors for clean color transitions, and with other warm tones for sophisticated color combinations. The four-foot length gives you ample material for major forms, and the diameter allows for confident manipulation at the torch while maintaining structural integrity throughout the build.
We do not cut anything over 38mm for the safety of our team members.
