The Grand is a stainless steel, surface mix bench burner with three separately controlled rings of fire. Each stage is controlled by two needle valves providing artists with unmatched control over flame size, heat potential and fuel mixture ratios. The Grand produces soft enveloping flames that gently bathe glass with a clean even heat. The torch can easily produce a wide range of flames; from small and gentle for fine detail stringer work, to flames large enough to fully encompass 11”+ diameter tubing. The torch is mounted on Bethlehem’s scroll base positioning arm, an upgrade form the traditional rack-n-pinion gear, enabling smooth torch adjustments that automatically lock in place. The Grand is the perfect all around torch for glass artists working wide ranges of glass, e.g. glass size, color, and density.
