Designed to fill the gap between the Alpha and Bravo Two Burners with independent gas controls Each burner comes with its own B-fitting gas and oxygen hose connections Each burner is constructed primarily of Stainless Steel Swivel base Each burner works independently of one another The Bethlehem Burners Stacks glass blowing torch is a dual-burner system created for artists who want more than the Alpha but aren’t quite ready for the Bravo. Each burner operates independently and features its own B-fitting gas and oxygen connections, letting users switch configurations or run both flames simultaneously. The stainless-steel construction supports long sessions, and the included swivel base adds flexibility in torch positioning. This glass torch includes the STACKS I top burner with 6 sharp flame jets and a 0.375″ face, while STACKS II delivers a broader flame from 18 jets and 48 oxygen ports across a 1″ face. It handles both precision and high-heat needs, suitable for 30 mm boro rods or 38 mm heavy-walled tubing. With separate gas controls, it’s possible to tailor each flame to match the task, making this lampworking torch a great addition to any setup. Designed with modularity in mind, the Bethlehem Burners Stacks glass blowing torch also comes with setup options to match specific needs, whether full kit or individual burner units.
