The STACKS - Bethlehem Burners

The STACKS bench burner was designed specifically to fill the gap between our Alpha burner and our Bravo burner. After taking 2 years for research and development, Bethlehem created the perfect in-between torch for both the beginner and the experienced flame worker!

Not only will The STACKS bench burner provide glass artists with a wide range of fuel mixtures, flame temperatures, and flame sizes, but it also provides them with purchasing options never before offered by Bethlehem Burners. The Top Mount and Bottom Mount can be purchased separately, thus giving flame workers the option to purchase The STACKS in stages.

Overview
Bethlehem Burners' first mid-range/mid-priced bench burner, The STACKS!

The STACKS bench burner was designed specifically to fill the gap between our Alpha burner and our Bravo burner. Not only will this torch provide glass artists with a wide range of fuel mixtures, flame temperatures, and flame sizes, but it also provides them with purchasing options never before offered by Bethlehem Burners.

Each burner is constructed primarily of stainless steel and is equipped with our one-of-kind, stainless steel modular needle valves. Each burner comes with its own B-fitting gas and oxygen hose connections, making each burner a complete and separate torch unto itself. The STACKS I (top mount) and works wonderfully with oxygen concentrators. Just like the Alpha and Bravo torches, these burners excel when fueled with a low-pressure system, making them the perfect torches for concentrators.
