Asian 44mm Transparent Black Tubing
ACT-BLTCT44
Asian-made borosilicate color tubing in a transparent black 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. Transparent black is commonly chosen when you want the depth and mood of black while still allowing light transmission and layered effects, making it useful for work where you want a darker tone that can still show internal volume, encased detail, or subtle transparency at thinner sections.
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 continuous dark color layer. Transparent black tubing is also useful for overlays and sleeving applications where you want a smoky, deep layer over compatible clear, and it can be stretched and necked down to create transitions and color bands while maintaining even color distribution through the forming process.
We do not cut anything over 38mm for the safety of our team members.
