Asian 44mm Cobalt Blue Tubing
ACT-BTC44
Asian-made borosilicate color tubing in a cobalt blue formulation, produced as a consistent, machine-drawn tube that provides a uniform hollow starting point for flameworking. Color tubing is used when you want continuous color coverage and a predictable wall without having to build a hollow form from solid rod, which saves time and helps keep wall thickness even as you inflate and shape. Cobalt blue is commonly chosen for work that needs a strong, saturated blue that reads clean and bold in finished pieces, offering high contrast against clear, white, and many bright transparent colors.
This tubing is used as a hollow blank for lampworking. A typical workflow is to cut a section, fire-polish the ends, and then either seal one end to form a bubble or attach a handle or blow tube so the tube can be evenly heated and inflated. The 44mm diameter is well-suited for larger hollow bodies such as vessels, jars, and sculptural components where you want substantial volume and a bold, uninterrupted color surface. Cobalt blue tubing is also useful for strong color bands, collars, and accent sections, and it can be stretched and necked down to create transitions while maintaining even color distribution through the forming process.
We do not cut anything over 38mm for the safety of our team members.
