Glasscraft is proud to provide the glassblowing community with a variety of quality borosilicate glass tubing in several price levels. We distribute Simax, Schott and Chinese glass in both clear and color. If your preferred brand is temporarily out of a specific size, we urge you to look for it in one of our other brands.
All of our borosilicate tubing and rod is measured in millimeters. Most of the sizes are presented in this format:
a x b x c for tubing or a x c for rod, like 25.4mm x 4mm x 1500mm ( 1" Extra-Heavy Tubing) or 3mm x 1500mm (3mm rod)
a = Outer diameter b = wall thickness c = length of the tube or rod, usually 4 or 5 feet long 1 inch = 25.4 millimeters
The inner diameter of a tube can be found by using: a - 2b, or the outer diameter subtracted by two times the wall thickness.
