Transparent glass tubes with a glossy surface, creating a luxurious play of light. High-temperature resistant grade (COE 3.3) made from pure borosilicate glass. Durable against thermal shock, it can comfortably withstand high-heat flames from an oxygen-propane torch without cracking.
Hollow tubes (tubing) with a 1.5-inch diameter, making them easy to blow, expand, shape, or pull into a taper. Ideal for functional glass art, large jewelry pieces, and modern design lamps.
