Asian 44mm Black Tubing
ACT-BLTC44
Asian-made borosilicate color tubing in a 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. Black tubing is commonly chosen for work that needs strong opacity, high contrast, and a clean silhouette, making it a staple for bold forms, graphic patterning, and pieces where the color must read clearly from a distance.
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 an uninterrupted dark color field. Black tubing is also frequently used for collars, mouthpieces, and accent sections, and it can be stretched, necked down, and joined to other compatible borosilicate colors to create sharp transitions and strong visual separation in assembled work.
We do not cut anything over 38mm for the safety of our team members.
